replicant_prepare_patch: subject prefix: add crude project names autodetection

For some projects, having the full repository name makes sense,
like for device_samsung_i9300, while for other the directory
structure can be omitted like libsamsung-ipc.

While the autodetection isn't complete, it at least handle
some common cases.
