libstdc++: Use IANA name for ISO-8859-1 in format tests.

Use IANA name for ISO-8859-1 as "-fexec-charset=" and add dg-require-iconv,
to make sure it is supported.

libstdc++-v3/ChangeLog:

	* testsuite/std/format/debug_nonunicode.cc: Pass ISO-8859-1 as
	exec-charset and make sure that it is supported.
	* testsuite/std/format/fill_nonunicode.cc: Likewise.
