Add wm-restack=generic option that lowers polybar to the bottom of the stack (#2404)

* Add wm-restack=generic to lower polybar to the bottom of the stack

Previously wm-restack only supported bspwm and i3. Both have a special
top-level window that polybar detects and places itself directly above.
This patch adds wm-restack=generic which simply lowers polybar to the
very bottom of the stack. This option was tested and confirmed to work
with xmonad which doesn't have a special top-level window and therefore
doesn't require special handling like bspwm and i3.

Fixes #2205

* Update src/components/bar.cpp
