Subject: [PATCH] Also search the LICENSE file in lib64/pythonX.Y

Several Linux distributions including Gentoo, Fedora, openSUSE
put things in lib64/pythonX.Y instead of lib/pythonX.Y on 64bit
architectures (x86_64, aarch64, etc.).

This was already respected via the fix_lib64() function, however
when virtualenv was searching for Python LICENSE, it was not.

Now is the lib64/pythonX.Y patch searched as well and unlike fix_lib64()
no checks need to be made, as the patch are tested in sequence.
