pw_transfer: Tidy up bazel proto imports

This change switches from relying on `copy_file` to using try/except to
import generated protos from the location bazel expects to find them.
This is less brittle: we're actually providing the generated code as a
dependency rather than tricking the build system into treating it as
opaque "data" that the Python interpreter will hopefully find at
runtime. In particular, it should actually work internally.

See the associated bug for a discussion of other options. This one has
the smallest blast radius.
