Use utf_8 'merge' encoding for all locales.
Previously, we used sys.getfilesystemencoding() for the 'merge'
encoding, but that had various problems:
1) If the locale is ever changed then it can cause orphan files due
to changed character set translation.
2) Ebuilds typically install files with utf_8 encoded file names,
and then portage would be forced to rename those files to match
sys.getfilesystemencoding(), possibly breaking things.
3) Automatic translation between encodings can lead to nonsensical
file names when the source encoding is unknown by portage.
4) It's inconvenient for ebuilds to convert the encodings of file
names themselves, and upstreams typically encode file names with
utf_8 encoding.
So, instead of relying on sys.getfilesystemencoding(), we avoid the above
problems by using a constant utf_8 'merge' encoding for all locales, as
discussed in bug #382199 and bug #381509.
