Skip definitions from the kernel on non-glibc Linux targets.
They're libc-independent, so we only need to check them on one
libc. We don't want to break CI if musl or another libc doesn't
have the definitions yet. (We do still want to check them on
every glibc target, though, as some of them can vary by
architecture.)
Update to the latest WASI libc, define `AT_FDCWD`, update the signature
for __wasilibc_find_relpath, and add declarations for various
`__wasilibc_` utility functions.
Remove unused iconv.h includes
These are left over from 3e4d684dcd, which
added includes to *all* platforms despite adding bindings only to *some*
of them. This already broke OpenBSD which doesn't have iconv.h (fixed by
915d8fac81), and is just distasteful, so
down with those unused includes.
(This is a continuation to #2037 and #2067.)
Add mount ID to statx
This mirrors the modifications to `include/uapi/linux/stat.h` by [Linux commit fa2fcf4f1df1559a0a4ee0f46915b496cc2ebf60 (“statx: add mount ID”)](https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=fa2fcf4f1df1559a0a4ee0f46915b496cc2ebf60).
What changed in v2 (v1: #2023):
* Skip testing the new `STATX_MNT_ID` constant, because it’s only part of Linux as of 5.8. That’s too new e.g. for Ubuntu 20.04.1 (with a kernel derived from 5.4), which is what’s used by the CI.
These are left over from 3e4d684dcd, which
added includes to *all* platforms despite adding bindings only to *some*
of them. This already broke OpenBSD which doesn't have iconv.h (fixed by
915d8fac81), and is just distasteful, so
down with those unused includes.
This corresponds to the Linux commit
fa2fcf4f1df1559a0a4ee0f46915b496cc2ebf60 ("statx: add mount ID").
Note that STATX_ALL is not modified to include this field, because it
has actually been deprecated in Linux and is now effectively defined as
equal to STATX_BASIC_STATS | STATX_BTIME (see Linux commit
581701b7efd60ba13d8a7eed60cbdd7fefaf6696, "uapi: deprecate STATX_ALL").
Because said commit fa2fcf4f1d is less than a year old, skip testing the
STATX_MNT_ID constant.

of SocketCAN functionality.

Add getrandom to FreeBSD
Introduced in FreeBSD 12.0.
Manual page: https://www.freebsd.org/cgi/man.cgi?query=getrandom.
Not sure if the constants should be `c_int`, just matching the `flags` argument in the function, in c they're macros.
Depending on the compilation environment (e.g., whether the 3XNET or
3SOCKET version of these functions is in play, whether EXTENSIONS has
been defined, etc) these functions may be declared to return either void
or int. The return value is hard coded as zero, and can be ignored to
better align with other platforms where these functions are always void.
We leave IPPROTO_MAX as is for the time being. However, in recent
kernel releases IPPROTO_MAX is actually higher and reflects the
addition of IPPROTO_MPTCP.
