x11/xlockmore: Update to 5.72

5.72
  Update for OpenVMS for x86_64, small change to xshm.h and new make.com
    to work with clang and xmlock/xawlock thanks to Jouk Jansen.  I hear
    its now possible to get a virtual OpenVMS on your Linux machine. :)
  Update for xscreensaver-6.06 port to use grabclient instead of
    grabscreen.
  configure now configures xmlock for Athena if you do not want Motif.
    Should work with most popular versions of Athena.  You may want
    to change the name from xmlock to xawlock if you are using Athena.
    xawlock directory removed and was not meant to be distributed.
