Bugzilla Bug 136159

app-emulation/xen-tools-3.0.2 installs both .py and .pyc files, but the .pyc
files are modified/overwritten during program execution so portage doesn't
remove them during the unmerge.

ebuild patch to use distutils eclass

The distutils eclass already addresses this problem, so I think using it is the
simplest solution.

I'm confirmed that when this patch is applyed the .pyc files are correctly
removed during unmerge.

Thanks. I've commited your patch.
