Getting rid of our remaining rhpl dependencies

[Jeremy Katz <katzj redhat com>]

So rhpl has over time turned into something of a dumping ground and
we're really not using it for much any more.  This probably means it's
getting close to its time to go away (much like was done with pythonlib
before).

Left in anaconda[1] are really just a couple of uses of rhpl
* rhpl.getArch() -- We mvoed this out of iutil, we could easily move it
back
* rhpl.simpleConfig -- I think this might be replaceable with
python-iniparse but I haven't looked to make sure
* rhpl.keyboard -- we use this in a few places and definitely would need
to do something for the consolidated keyboard list.  But
system-config-keyboard might be the better place for this to live

Anyone else have any opinions or want to look at any of the above?

[1] The biggest thing was rhpl.translate, but I moved everything to just
use the gettext module directly today.
