Fix test cases tst-fnmatch and tst-regexloc for the new iso14651_t1_common file.

Therefore, using [a-z] does not make much sense except in the C/POSIX locale.
The new iso14651_t1_common lists upper case and  lower case Latin characters
in a different order than the old one which causes surprising results
for example in the de_DE locale: [a-z] now includes A because A comes
after a in iso14651_t1_common but does not include Z because that comes
after z in iso14651_t1_common.

	* posix/tst-fnmatch.input: Fix results for range expressions
        for non C locales.
	* posix/tst-regexloc.c: Do not use a range expression for
        de_DE.ISO-8859-1 locale.
