chardev: let g_idle_add() be with chardev gcontext
The idle task will be attached to main gcontext even if the chardev
backend is running in another gcontext. Fix the only caller by
extending the g_idle_add() logic into the more powerful
g_source_attach(). It's basically g_idle_add_full() implementation, but
with the chardev's gcontext passed in.
