ld: Limit "readelf --got-contents" tests

Since "readelf --got-contents" tests use -melf_i386, -melf_x86_64 and
-melf32_x86_64 emulations, limit theses tests to linker supporting those
emulations, pass --rosegment to linker and output libgot-1-i386.so,
libgot-1-x64.so, libgot-1-x32.so.

	PR ld/33350
	* testsuite/ld-i386/binutils.exp: Limit tests to linker with
	-melf_i386 support, pass --rosegment to linker and output
	libgot-1-i386.so.
	* testsuite/ld-x86-64/binutils.exp: Limit -melf_x86_64 tests to
	linker with -melf_x86_64 support, limit -melf32_x86_64 tests
	to linker with -melf32_x86_64 support, pass --rosegment to
	linker and output libgot-1-x64.so/libgot-1-x32.so.
