package/gpsd: enable python support and modules
Add option that enables gpsd python support including modules, tools,
and gpsfake test harness. If python is enabled then install python
modules unconditionally. Note that gpsd python modules run compatibly
under Python 2 and 3.x for x >= 2. So enable gpsd python support when
any Python version is enabled in board configuration. If no Python is
enabled, but gpsd Python support is requested, then select Python 3.
