Allow a device config to include its own libril sourcecm-7.1.0cm-7.0.3cm-7.0.2.1cm-7.0.1cm-7.0.0gingerbread-releasegingerbreadgb-release-7.2

There's a number of reasons to use an alternate libril:
* Older RIL blobs with incompatible ABIs
* Vendors that don't quite follow the documented API
* Devices derived from CAF code (which has some differences to
Google's versions)
* Probably others...

If a BoardConfig includes a TARGET_PROVIDES_LIBRIL, this
will make it build libril using the code that's in <device-dir>/libril
instead of hardware/ril/libril.

Alternatively, that variable can contain the full path to the
alternative libril
