x11/phosh: remove incomplete port
pkg-descr said "Currently, only useful for developers." Phosh itself
has many features stubbed and also depends on GNOME/Wayland which
isn't supported on FreeBSD yet. Avoid confusing users by putting
the port out of misery.
x11/phosh: add new port
Phosh aims to be a Wayland shell for mobile phones. Currently, only
