xdotool: Update x11/xdotool to 3.20160805

pkgsrc changes:
 - Update MASTER_SITES
 - Remove unused USE_LIBTOOL (libtool was not and is not used)
 - Only pod2man is needed as a tool, avoid to include perl bl3

Changes:
3.20160805.1
  - Fix release tool problem. cflags.sh was missing from the previous two
    releases.
    `make test-package-build` now works correctly on OSX 10.11 and Fedora 23.

3.20160804.2
  - Fix some bugs in the Makefile especially for OS X / macOS Sierra
    (Misty De Meo)

3.20160804.1
  - Fix compilation problems on OSX 10.12 aka macOS Sierra. (#138; Jordan
    Sissel and Misty De Meo)
  - Fix memory leaks in window search and charcode map lookups (Markus Roth)
  - xdotool selectwindow (xdo_select_window_with_click) now only selects the
    window if mouse button 1 is pressed. Any other buttons will cause this
    selection to be aborted. (#136, #137; Jordan Sissel and Yuri D'Elia)
  - Fix bug where `xdotool click` with --clearmodifiers can sometimes leave
    stuck keys or mouse buttons. (#102, Aurelien Lourot)
  - windowmove now supports coordinates as a percentage of screen size. For
    example, a move to 50% 50% would move the window such that the top-left
    corner of the window is in the center of the screen. (#92, #27; Collin
    Guarino)
  - Typing commands (key and type) will now try to use XTEST instead of
    XSendEvent in a special circumstance. If the window id given (by window
    stack or the --window flag) is the currenly-focused window, key sequences
    will be sent using XTEST. (#85, mpnolan)
  - getmouselocation, getwindowgeometry, and search commands: now supports
    --shell and --prefix for having stdout be consumable by bash or similar
    shells. (#80, yatsek)
  - xdotool scripts such as running via `xdotool -` will now execute commands
    as lines of input are read. The previous behavior waited until stdin closed
    before executing anything. (#131, abensj)

3.20150503
  - Lots of changes over the past 4 years, but with many folks telling me to do
    another release tarball, here it is.
    We can backfill the changelog later.
