Add support for packaging python "distributions" that use distutils.

Suppport conditional PLIST inclusion of the expected egg file, because
python2.4 distutils does not create them but later versions do.  (Note
that PRINT_PLIST_AWK production is not working, probably due to order
of substitution.)

Earlier patch reviewed by wiz@.
