This patch fixes issues during package build with ebuild supporting
installation for Python versions: sed substitutions in common.py and location
of ufw script in Python ABIs which have prefix different than /usr.
Also makes .mo files not to be installed in wrong paths.

More info about the first issue:
with support for multiple Python versions in the ebuild, seems the
file isn't copied from staging/ to build-*/lib/ufw/ after being
modified. That's why the copy needs to be done "manually" here.
The issue occurs with "setup.py build -b build-XXX" followed by
"setup.py build -b build-XXX install".
