genmatch: Fix build on hppa64-hpux [PR117348]

Apparently autoconf defines the HAVE_DECL_* macros to 0
rather than not defining them at all, so defined(HAVE_DECL_FMEMOPEN)
test doesn't do much.

The following patch fixes it by testing HAVE_DECL_FMEMOPEN
for being non-zero instead.

	PR middle-end/117348
	* genmatch.cc: Replace defined(HAVE_DECL_FMEMOPEN)
	test with HAVE_DECL_FMEMOPEN.
