Issue #17429: platform.linux_distribution() now decodes files from the UTF-8

encoding with the surrogateescape error handler, instead of decoding from the
locale encoding in strict mode. It fixes the function on Fedora 19 which is
probably the first major distribution release with a non-ASCII name. Patch
written by Toshio Kuratomi.
