Give KLEE release version information in the output of klee and kleaver

when they are given the --version command line option.

Unfortunately to make the build type and git revision available we
need to check this for every build which means KLEE's support library
will be rebuilt for every build which will slow down incremental builds.

This addresses issue #231
