python: egg.mk: add USE_PKG_RESOURCES flag

This flag should be set for packages that import pkg_resources
and thus need setuptools after the build step.

Set this flag for packages that need it and bump PKGREVISION.

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

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