[committed] Fix LD_LIBRARY_PATH setting in libgomp fortran.exp testing (PR libgomp/47804)

[Jakub Jelinek]

Hi!

The recent change resulted in libgfortran/.libs not being added
into LD_LIBRARY_PATH for fortran libgomp testing if libquadmath
didn't exist, which is wrong.
Additionally, similarly to the earlier checks in fortran.exp we should
test both libquadmath.a and libquadmath.${shlib_ext} presence.

Bootstrapped/regtested on x86_64-linux and i686-linux, manually tested
with removing libquadmath.a, then also libquadmath.so, committed to trunk.

	* testsuite/libgomp.fortran/fortran.exp: Check for both
	libquadmath.a and libquadmath.${shlib_ext}.  If neither exists,
	but $blddir != "", still append ${blddir}/${lang_library_path}
	to ld_library_path.
