nxcomp: Hardcode X11 and (legacy/xfs) font UNIX paths.

Fixes: ArcticaProject/nx-libs#536

Allowing overrides via NX_TEMP and TEMP breaks system using
pam_tmpdir.so and most server infrastructure expects the location to be
fixed anyway.

Backported from Arctica GH 3.6.x branch.

v2: backport to nx-libs 3.5.0.x (Mihai Moldovan)

Adds:
  - debian/patches/1610_nxcomp-harcode-some-UNIX-socket-path.full+lite.patch
