0.22: missing dependencies in intl

[Christian Weisgerber]

Building gettext-runtime/intl with make -j reveals some missing
dependencies:

In file included from ./log.c:24:
./gettextP.h:71:11: fatal error: 'libgnuintl.h' file not found
# include "libgnuintl.h"
          ^~~~~~~~~~~~~~
In file included from ./langprefs.c:25:
./gettextP.h:71:11: fatal error: 'libgnuintl.h' file not found
# include "libgnuintl.h"
          ^~~~~~~~~~~~~~

log.c and langprefs.c include gettextP.h, which in turn requires
libgnuintl.h.  The explicit dependencies in Makefile.am need to
reflect this:
