Add libnimbus_experimenter.so to experimenter (#9455)

Because

- we haven't yet cross compiled libnimbus_experimenter.so for developer
machines

This commit

- Adds an extra git checkout / cargo build to get
libnimbus_experimener.so into experimenter.

N.B. this uses the `--library` form of `uniffi_bindgen`. Once lands, we
should remove the `cdylib_name` entries in the FML and Nimbus
`uniffi.toml` files in application-services.
