Fixes ArcticaProject/nx-libs#250.

Upstream does not use xkbfile but has own copies of the required
files. It was not used elsewhere.

nx-X11/config/cf/lnxLib.tmpl requires post-library removal cleanup: Drop references to dropped X11 extension client libraries.

Fixes ArcticaProject/nx-libs#115.

imake clean-up: Enforce build of Mesa GLX extension. Drop all other GLX build methods (built-in DRI drivers, etc.).

libX11 underlinking problem: Fix undefined reference to 'XdmcpWrap' (by linking against X.Org'x libXdmcp).

  We really want to make use of rpm's automatic dependency finding.
  Binaries are scanned for DT_NEEDED entries, the latter of which are
  then used for populating the "Requires"-type deps. The "nxagent"
  binary for example would require libX11.so.6. That incurs problems:

  1. A package manager told to install nxagent could select xorg-x11
  rather than nx-libs, even though nxagent depends on the NX version.

  2. A package manager told to install $some_program could select nx-libs
  rather than xorg-x11 (since both provide libX11.so.6), but, since
  the NX library is in an obscure directory, running $some_program
  would fail as libX11.so.6 is not found.

  To solve this, give the NX libraries unique names different from the
  Xorg ones.

This reverts commit e77bf36d.
