Backport gettext fixes to get rid of warnings on macOS

Two fixes were committed recently to the gettext repo in order to make
gdb build warning-free on macOS.  This patch backports them both:

  - Make the format_arg attribute effective also in the case _INTL_REDIRECT_INLINE.

  - Enable the format_arg attribute also on clang on Mac OS X.
