[Xcb] [PATCH 1/2] Remove unused DECnet code

[Alan Coopersmith]

"unifdef -UDNETCONN src/xcb_util.c" plus re-indenting code that was
formerly in the else clause after a DECnet check.

DECnet support has been removed from most of the X.Org code base for
several years, and it appears DNETCONN was never defined in XCB.
