Michael Forney b1d2e476e9 linux-user: Remove obsolete F_SHLCK and F_EXLCK translation
These lock types are unsupported by Linux since v2.2[0][1] and
always return EINVAL (except on SPARC up until v2.6, which just
warned).

musl libc does not define these constants, so just remove them from
the translation cases.
