Fix MIPS sa_flags type (bug 17781).

sysdeps/unix/sysv/linux/mips/bits/sigaction.h gives sa_flags type
unsigned int, but POSIX says it should be signed int.  This patch
gives it the correct type (the layout is unchanged, so there are no
ABI issues involved).

	[BZ #17781]
	* sysdeps/unix/sysv/linux/mips/bits/sigaction.h
	(struct sigaction): Change type of sa_flags field to int.
