[igt-dev] [PATCH i-g-t 1/2] lib/igt_kmod: fill skip message for KUnit skips

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

IGT build is currently complaining with the lack of a message for
igt_skip:

  [188/1383] Compiling C object lib/libigt-igt_kmod_c.a.p/igt_kmod.c.o
  ../lib/igt_kmod.c: In function ‘__igt_kunit’:
  ../lib/igt_kmod.c:847:26: warning: zero-length gnu_printf format string [-Wformat-zero-length]
    847 |                 igt_skip("");
        |                          ^~

Add one.
