rbconfig.rb: use program version

* common.mk, tool/mkconfig.rb: check the running ruby version in
  rbconfig.rb with the program version, as RUBY_VERSION has never
  been affected by --with-ruby-version option.
  [ruby-core:68639] [Bug #11002]
* configure.in (LIBRUBY_DLDFLAGS): compatibility_version must be
  valid version numbers, not an arbitrary string.
