Rolf Eike Beer 409aeafa25 FindRuby: do not blindly set version to 1.8.0 ...

RUBY_VERSION was always set, even if no RUBY_EXECUTABLE was found. While it
may make sense to assume a default version if we can't execute the binary, it
certainly doesn't make sense to report a version if there is no executable at
all.
