clean up gl-install

- move wrap_mkdir() to gitolite.pm
  - remove junk left over from days when dinosaurs ruled the world
  - reuse setup_environment() from gitolite.pm instead of rolling our
    own code for PATH and umask
    part of it's function (the rest is harmless)

  - and most important, remove the last vestiges of the old 'from
    client' install method, in the form of 'if ($GL_PACKAGE_HOOKS)'
    lines

  - clean up the symlinking to be more precisely in line with
    doc/hook-propagation.mkd (especially, remove the 'quirk' that
    package hooks would also get copied to the user hooks area)
