Make nxagent process aware of its current NX'ish version.

  This feature copies the way how X.Org version string and number
  are propagated at build time.

  First use case: if people start nxagent, it reports its version number
  on stderr. This is about being human-friendly.

  Second use case: None, so far. But it will now be easy to use
  the NXAGENT_VERSION_STRING in later feature add-ons.
