i18n: fix exgettext handling of C++ sources

The move of source files to .cc names broke most message extraction by
exgettext because it processed .c files with --language=GCC-source but
didn't process .cc files that way.  Fix to process files identified as
C++ that way as well.

Tested with "make gcc.pot".

	* exgettext: Also process C++ sources with --language=GCC-source.
