Simplify autogen.sh version checking

* autogen.sh (get_version): Simplify and make more reliable
by using expr rather than echo | sed.  Check exit status of program.
Run program in subshell in case it cannot be executed.
(check_version): Check exit status of command rather than its output.
Check return status of get_version.
