x11/xlockmore: Update to 5.70

Patch for configure script adapted.

5.70
  Patch for Cannabidiol and Fentanyl from Richard Narron, richard AT
    aaazen.com.
  I was able to get DtScreen to work on Linux with CDE with slight
    modification to Makefile (documented in README) with help from Per
    Backman, 229pele AT tufftuff.net.
  xmlock updates for Athena.  In generated Makefile will have to change
    HAVE_MOTIF to HAVE_ATHENA and change -lXm to -lXaw or -lXaw3d.  Just
    bare bones right now.
  t3d.c: following recommendated change for configure "warning: Update your
    code to rely only on HAVE_SYS_TIME_H".  Also other assorted changes
    in configure.ac when I ran autoupdate (did not accept everything as
    it seemed to go wrong).
