meson.build: Fix docker-test-build@alpine when including linux/errqueue.h 

A build error happens in alpine CI when linux/errqueue.h is included
in io/channel-socket.c, due to redefining of 'struct __kernel_timespec':

===
ninja: job failed: [...]

                 from ../io/channel-socket.c:29:
/usr/include/linux/time_types.h:7:8: error: redefinition of 'struct __kernel_timespec'

As above error message suggests, 'struct __kernel_timespec' was already
defined by liburing/compat.h.

Fix alpine CI by adding test to disable liburing in configure step if a
redefinition happens between linux/errqueue.h and liburing/compat.h.

[dgilbert: This has been fixed in Alpine issue 13813 and liburing]
