Use local gioui fork with the Android re-attach ack fix

Browse Source 
gioui v0.10.2's onCreateView sends the window handshake ack
(mainWindow.windows <- struct{}{}) unconditionally on the UI thread. On
activity re-attach (relaunch after task wipe, config-change recreation)
the only receiver (newWindow via Window.init) never re-runs, so the send
blocks the UI thread forever in onCreate: the activity never gets an
input channel and the app is a live-but-unresponsive black screen.

The fork at /home/gmp/gioui-v0.10.2 (branch android-reattach-ack) moves
the send into the first-window-creation branch. Same fix as the pad app.
