getopt: merge from gnulib: don't use `...' quotes 

I'm not sure whether this is official GNU style now, but `...' quotes
haven't looked properly balanced in most people's terminal fonts since
2001ish? and gnulib has chosen to switch over to '...' quotes.
I'm merging this separately from the other changes in gnulib because
it's very mechanical.

	* posix/getopt.c, posix/getopt.h, posix/getopt1.c, posix/getopt_int.h:
	Use '...' instead of `...' for quotation marks inside
	comments and strings.
