sim/configs:use [HAL]HALFILE=LIB: (3 hallib items)

configs/sim/axis/moveoff/*.ini         [HAL]HALFILE = LIB:hookup_moveoff.tcl
                                       [HAL]HALFILE = LIB:moveoff_external.hal
configs/sim/touchy/ngcgui/*moveoff.ini [HAL]HALFILE = LIB:hookup_moveoff.tcl
configs/sim/axis/xhc-hb04/*.ini        [HAL]HALFILE = LIB:xhc-hb04.tcl

to accomplish this:
  1) mv the referenced files to lib/hallib (new directory)
  2) remove obsolete soft links
  2) modify the ini files to use LIB:
  3) update README, .txt files

also: monitor_xhc-hb04.tcl moved to scripts and renamed for consistency

note: for deb building at least one of each .hal, .tcl are required
      in lib/hallib/
