ports/unix/check: Ignore error from fail_* macros

Browse Source 
Usage of fail_if/fail_unless macros with a message results in a
warning with the latest version of check (0.15.2+) and GCC.

Ignore this specific error (since warnings are treated as errors) for now.

Example failure:

In file included from ../../../../src/../test/unit/lwip_check.h:7,
                 from ../../../../src/../test/unit/lwip_unittests.c:1:
../../../../src/../test/unit/lwip_unittests.c: In function ‘lwip_check_ensure_no_alloc’:
../../../../src/../test/unit/lwip_unittests.c:55:7: error: too many arguments for format [-Werror=format-extra-args]
   55 |       "mem heap still has %d bytes allocated", lwip_stats.mem.used);
      |       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
