Adhemerval Zanella 802c1c5a65 posix: Correctly block/unblock all signals on Linux posix_spawn ...

This patch correctly block and unblocks all signals when executing
Linux posix_spawn by using the __libc_signal_{un}block_all functions
instead of default sigprocmask.  The latter might remove both
SIGCANCEL and SIGSETXID from the blocked signal list.

Checked on x86_64, i686, powerpc64le, and aarch64.

	* sysdeps/unix/sysv/linux/spawni.c (__spawnix): Correctly block and unblock
	all signals when executing the clone vfork child.
	(SIGALL_SET): Remove macro.
