plugins: keepkey: rm dependence on external keepkeylib

we will instead bundle our own fork, as a git submodule,
https://github.com/spesmilo/electrum-keepkeylib

related https://github.com/spesmilo/electrum/issues/7922
and https://github.com/keepkey/python-keepkey/issues/146
(i.e. upstream keepkeylib is unmaintained)
