remove implementation-reserved bits when saving signal mask

this fix is necessary because a program could be started with some of the implementation-reserved signals masked (e.g. due to exec having been called from a signal handler, or from a non-musl program) and then could obtain an invalid-to-use-later sigset_t as the old/saved signal mask.
