[Buildroot] [git commit] package/python-networkx: install for host-python3

commit: https://git.buildroot.net/buildroot/commit/?id=f202b2369190661cb224e5871afc30bf5d85dce1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This Python module only works for Python 3: the target variant has a
"depends on BR2_PACKAGE_PYTHON3".

However today in Buildroot, when no target python is selected, or when
BR2_PACKAGE_PYTHON=y, all host python modules are installed for
host-python, i.e Python 2. But this module won't install in Python 2,
so let's force its host variant to be installed with Python 3 on the
host. Of course, for that to work, its dependency must also be built
for host-python3, so we change it to the newly introduced
host-python3-decorator package.

Fixes:
