Subject: [PATCH] build(doxygen): fix Doxygen failure in case of tarballs
 (#462)

- The version information file for Doxygen (version.sh.in) should be put
  into a tarball even when Doxygen is unavailable in the system where
  the tarball is created.

- version.sh is not needed for a tarball (version.sh.in is).

- The fallback in the absence of version information in configure.ac
  must also consider version.sh.in.

Close #462.
