[PATCH 1/2] package/package_manager: multiprocess_exec -> multiprocess_launch

[Richard Purdie <richard.purdie@linuxfoundation.org>]

After this replacement, the parent exception handling works so we don't
need subprocess wrapping with bb.error in the underlying functions.

The underlying contexts also have better module handling so the imports
can be cleaned up.
