selftest: af_unix: Support compilers without flex-array-member-not-at-end support

Browse Source 
Fix:

gcc: error: unrecognized command-line option ‘-Wflex-array-member-not-at-end’

by making the compiler option dependent on its support.

Fixes: 1838731f10 ("selftest: af_unix: Add -Wall and -Wflex-array-member-not-at-end to CFLAGS.")
