libsemanage/tests: misc cleanup

* Explicitly mark unused function parameters and drop compiler warning override * Move declaration of `semanage_handle_t *sh` from individual source files to utilities.h, since it is defined in utilities.c * Declare file local variables static * Drop unused macros * Avoid casts dropping const qualifier * Avoid usage of reserved identifier names (leading underscores) * Silence UBSAN underflow warning by adding explicit cast Signed-off-by: Christian Göttsche <cgzones@googlemail.com> Acked-by: James Carter <jwcart2@gmail.com>
