Generate Android.bp for oneshot-uniffi

The crate is a bit special: it’s identical to the oneshot crate, but
with a dependency removed:
https://github.com/faern/oneshot/compare/main...bendk:oneshot:main

As such, the crate is called oneshot-uniffi, but the rest of the
UniFFI crates import it as just “oneshot”. The same applies to the
tests in the crate itself.

Patching the `crate_name` seems like the easiest way to accommodate
this. The library is visibility restricted so this will only be
visible to `uniffi_core`.
