Ryan Houdek da0a1710c0 CMake: Fix pkg version extraction
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.
