Update 1.0 to 1.2 based on PR pkg/49063 by Leonardo Taccari.
(pkgsrc)
  - Instead of using do-* in Makefile adjust config.mk and use the
    official Makefile like other suckless.org packages (e.g. x11/dmenu).
  - Do not install README: the only useful information for the user was:
    Simply invoke the 'slock' command. To get out of it, enter your
    password. The user can read that in x11/slock/DESCR by
    pkg_info slock.
(upstream)
  * slock-1.2:
