Clean up trivially redundant __USE_MISC conditionals.

Browse Source 
This patch cleans up cases of __USE_MISC that are trivially redundant
after the recent substitution of __USE_MISC for __USE_BSD and
__USE_SVID: either in constructs such as "defined __USE_MISC ||
defined __USE_MISC", or else (in the bits/mman.h case) a conditional
on __USE_MISC nested inside another __USE_MISC conditional.  (The
cleanups remaining after this patch are still quite large, but it
seems a reasonable piece to separate out.)

Tested x86_64.

	* bits/mman.h [__USE_MISC]: Remove redundant conditionals.
	* ctype/ctype.h [__USE_MISC]: Likewise.
