[test] Improve ParseableInterfaceImports check patterns (#70519)
When one configures their toolchain to use a define (`-D`) in either
`SWIFT_FRONTEND_TEST_OPTIONS` or `SWIFT_DRIVER_TEST_OPTIONS`, the
DIModule generated by this test might have other elements like
`configMacros` in between `name:` and `includePath:`.
To account for this possibility, break the check in two, using
`CHECK-SAME` for the second part.
