[LTP] [PATCH v2] syscalls/semctl09: Skip libc test if SEM_STAT_ANY not defined

[Martin Doucha]

The libc test variant should run only if system headers define SEM_STAT_ANY.
Skip it if we're falling back to the LAPI definition.

Changes since v2:
- move test_info() call before #if to make test output more clear
