Add comment about sigaction sa_restorer field
* os_dep.c (GC_find_limit_openbsd, GC_skip_hole_openbsd,
GC_set_and_save_fault_handler, GC_dirty_init): Add comment about
sigaction sa_restorer field initialization (some static code analysis
tools report about uninitialized field but according to Linux manual
it is obsolete and should not be used).
* pthread_stop_world.c (GC_stop_init): Likewise.
