Log message:
python: remove Python 2.7 from the default build set

Set PYTHON_27_ACCEPTED for packages where 2.7 needs to be supported
because other 2.7 packages depend on it, but it also supports 3.x.

Tested by jperkin, thanks!

Log message:
*: bump PKGREVISION for egg.mk users

They now have a tool dependency on py-setuptools instead of a DEPENDS
