tests: gate t-verify-self-spf on TEST_SPF conditional (#412)

The test requires SPFSelfValidate support compiled in (--with-spf) but
was included unconditionally in LIVE_TESTS, causing it to always fail
rather than skip when SPF support is absent.  Move it inside TEST_SPF
so it only runs when the feature is actually enabled.

Fixes #411.
