Increase root installer timeout from 5 to 30s. Fixes Issue #74.

The superuser shell has a timeout that can be specified. The timeout
was set to 5 seconds, thus the exit code from the shell is -1 (a
reserved exit code used by libsuperuse to indicate timeout).

By my estimate, it is more likely that a user will hit this error
message and get annoyed, compared to actually hitting a genuine timeout
because of some issue with superuser. Especially when we factor in slow
devices and large apps to install. Thus, the timeout has been bumped
to a more generous 30 seconds.
