Attributes GH PR #313: https://github.com/ArcticaProject/nx-libs/pull/313

Makefile: Fix flawed uninstall-* targets. Spotted by Ionic while reviewing the nxagent RPATH changeset. Thanks!

debian/patches: Update 016_nx-X11_install-location.debian.patch. Adapt path to recent upstream changes.

Load libNX_X11 / faked libX11 via RPATH setting rather than fidgeting with LD_LIBRARY_PATH in the nxagent wrapper script.

 Fixes ArcticaProject/nx-libs#225.

  SHLIBDIR -> Points to the system's official library folder.
  USRLIBDIR -> In NX, this variable (amongst others) is used to set
               the executables RPATH (if enabled), so pointing this
               to SHLIBDIR/nx-X11.

debian/rules: Don't manually override SHLIBDIR via the dh_auto_build call. The default in the main Makefile should work fine.

nx-libs.spec: Don't manually override SHLIBDIR via the .spec file. The default in the main Makefile should work fine.

Makefile: Align variable names USRLIBDIR, SHLIBDIR (and NX_DIR) with nx-X11 internal naming schemes (and use /usr/<lib>/nx/X11 rather than /usr/<lib>/nx-X11).

nx-X11/include/Xos_r.h: Drop one _POSIX_REENTRANT_FUNCTIONS macro block, where offenders AIXV3, AIXV4 and __osf__ are gone now.

debian/copyright{,.in}: Adopt from Debian's upload candidate, being DEP-5 compliant and up-to-date for 3.5.99.3.

 Fixes ArcticaProject/nx-libs#2.

Makefile: Don't create superfluous symlink for libX11.so -> ../libNX_X11.so. The libNX_X11.so is only required at build time, so need to use it for faking libX11.so in nxagent.
