[Buildroot] [git commit branch/2020.02.x] package/python-pycryptodomex: add host variant

commit: https://git.buildroot.net/buildroot/commit/?id=c904fd033c0d7d974a951d714ccf6fb83689374e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

Adding a host variant will allow to replace host-python-pycrypto by
host-python-pycryptodomex for the crda and optee-os packages.

From [1]:
"PyCryptodome is a fork of PyCrypto, which is not maintained any more
(the last release dates back to 2013 [2]). It exposes almost the same
API, but there are a few incompatibilities [3]."
