lib/oe/lsb: sanitise the distro identifier

The distribution identifier is often used to create filenames, so it needs to be
safe to use as a filename.  Whilst most distributions have e.g. Fedora or Debian
as their name, it is possible that the name contains special characters.

To ensure this doesn't cause a problem strip out any non-alphanumerics from the
distribution name before returning it.
