Fix MIPS variable PAGE_SIZE bug (16191)

MIPS supports a variable page size but glibc defines a constant.
This causes at least two glibc tests to fail when the page size
does not match the hard-coded size:

inet/test-ifaddrs
inet/test_ifindex

	[BZ #16191]
	* NEWS: Mention bug fix.
	* sysdeps/unix/sysv/linux/mips/sys/user.h (PAGE_SHIFT): Remove.
	(PAGE_SIZE, PAGE_MASK, NBPG, UPAGES): Likewise.
	(HOST_TEXT_START_ADDR, HOST_DATA_START_ADDR): Likewise.
	(HOST_STACK_END_ADDR): Likewise.
