MIPS/GAS/testsuite: Tighten negative-match NaN tests

Fix a test quality regression introduced with commit 351cdf24 [[MIPS]
Implement O32 FPXX, FP64 and FP64A ABI extensions] where MIPS ABI flags
match patterns have been added to negative-match tests covering ELF file
header flags.  Negative-match tests succeed whenever there is a failure
in matching output produced and consequently the likelihood of a false
success increases when patterns to match irrelevant output are added.

Therefore remove the irrelevant paterns so that the tests complete as
soon as the line concerned has been seen.

	* gas/mips/nan-legacy-1.d: Remove MIPS ABI flags match patterns.
	* gas/mips/nan-legacy-2.d: Likewise.
	* gas/mips/nan-legacy-3.d: Likewise.
	* gas/mips/nan-legacy-4.d: Likewise.
	* gas/mips/nan-legacy-5.d: Likewise.
