Drop nan-pseudo-number.h usage from tests

Make the tests use TEST_COND_intel96 to decide on whether to build the
unnormal tests instead of the macro in nan-pseudo-number.h and then
drop the header inclusion.  This unbreaks test runs on all
architectures that do not have ldbl-96.

Also drop the HANDLE_PSEUDO_NUMBERS macro since it is not used
anywhere.
