navbar: show menu if nav bars are force enabled via property

users can force enable navigation bars, via setting the
property "qemu.hw.mainkeys=0".
after a reboot, they have fully functional navigation bars.

unfortunatly the omnigears setting doesnt recognize them, as it
doesnt check for it.

lets check for this property and let users, which force enable
their navigation bar, enjoy the option to customize them.
