Fix fc-prototypes usage with C_INT64_T and non LP64 Targets.

The problem here is we were outputing long_long instead of
"long long". This was just an oversight and a missing check.

Committed as obvious after a bootstrap/test on x86_64-linux-gnu.

gcc/fortran/ChangeLog:

	* dump-parse-tree.cc (get_c_type_name): Fix "long_long"
	type name to be "long long". Add a comment on why adding
	2 to the name too.
