Render Android hourglass cursor mechanics more consistent with X

* src/androidterm.c (android_show_hourglass): Always define the
hourglass cursor, but...
(android_hide_hourglass): ... restore the invisible cursor
subsequently, if need be.
(android_toggle_visible_pointer): Do not hide the current cursor
if it is an hourglass.
