Update python dependencies to be simply to "python"

Previously python dependencies were of the format "python(abi) = ..."
This format is not yet supportable within OE, so revert to a form
we know we can handle.

Introduce a change to package.bbclass that ensures it will causes the
sstate-cache's "package" to invalidate.  Since pythondeps changed, the
output of rpmdeps changes, which causes the per-file dependency
information to change.... thus we need to invalidate the cache!
