Passthrough services: lookup multiple names.

Lookup passthrough services which start with the required name. This
will allow vendors to define passthrough modules (for instance
android.hardware.xyz@1.0-impl-$(vendor).so) to avoid build system
collisions and have a custom passthrough implementation.

Bug: 34366227
Test: hidl_test, full make, nfc works, manual test that a renamed
passthrough implementation is properly loaded.
