Minor adjustments to Android port stubs

Browse source 
* src/androidfns.c (Fx_display_backing_store): Return
`when-mapped' in place of `always', since the former better
reflects Android port behavior.
(syms_of_androidfns) <always>: Delete defsym.
<when-mapped>: New defsym.

* src/term.c (Fsuspend_tty, Fresume_tty): Properly signal errors
on Android rather than quietly disregarding calls.
