Our regex would only ever capture a single digit, so versions that had more than one digit per section would lose additional digits. Fixes and moves the helper to a cmake file to be shared between GuestLibs and HostLibs. Uses the fix in xcb because Fedora ships an older version that doesn't have some of FEX's newer symbols.
