[LTP] [PATCH] lib: Add include guard to tst_safe_clocks.h

[Rafael David Tinoco]

When adding a common header to my tests I missed this include guard when
accidentally including tst_safe_clocks.h from .c and .h files. Since
other tst_safe_*.h files have guards I thought it would be good to add
to this one as well.
