MIPS/LD/testsuite: Run `got-dump-1' for o32/n32 ABIs

The `got-dump-1' test case uses 32-bit addressing, so it makes no sense
to run it with the n64 ABI.  And there is a corresponding `got-dump-2'
test already for the n64 ABI.

Use the per-ABI framework then to run the `got-dump-1' test explicitly
for o32 and n32 ABIs only.
