[Buildroot] [PATCH] python-lxml: allow build as host package

[Carlos Santos]

While currently there is no in-tree Buildroot package which depends on
host-python-lxml, we (DATACOM) have some proprietary modules that use it
in their test scripts.

We tested python-lxml as host package and confirmed that it builds and
works correctly. Someone else might require it, so we are proposing its
inclusion.

Additional background (DATACOM-specific): so far we circumvent the lack
of host-python-lxml invoking python with an absolute path in the tests
(/usr/bin/python) but this forces us to install python-lxml on all build
hosts and developer workstations.
