unit-test.py: Test PDI with additional options

When phosphor-dbus-interfaces is under test, enable the org.open_power
and com.ibm interfaces so they get built as well.

Just did this for meson since both meson and autotools run under CI and
the results should be the same, plus the autotools build may soon go
away.
