Better check for the fork emulation in t/win32/signal.t

The d_pseudofork Configure variable hasn't been around all that long so
isn't suitable for use in dual-lived module tests, but is good for use in
core tests.

(t/win32/runenv.t doesn't do this since it is actually PERL_IMPLICIT_SYS
rather than the fork emulation which that test requires.)
