packagegroup-builder: package all of python
packagegroup-builder: package all of python

Based on oe-core commit 745dfbc869fd593d1b92e2bc9c01d589ab21ade3
"buildtools-tarball: package all of Python", we do the same here
for packagegroup-builder.

The switch to the fetcher where it added BeautifulSoup revealed
a shortcoming in the python packaged for the self hosting (missing
htmlentitydefs).  Here we fix it in the same way as what was done
for buildtools-tarball and include python-modules vs. all the
individual little chunks.
