[dev.unified] test: relax live_regabi.go

Unified IR will soon introduce additional temporary variables for
multi-valued expressions, which cause this test to start failing.
However, according to the comment on lines 594--596, we don't care
what temporaries are printed on the noisy lines, just that they're not
mentioned on the printnl lines.

This CL relaxes the test expectations so that temporaries are allowed
to be live at the call to fb38() too, not just the calls to fi38() and
fc38().
