adb-remount-test add --no-wait-screen option

If the device screen drivers or frameworks are compromised, permit
remount testing without waiting for full boot complete to occur with
the --no-wait-screen option.  In the same vein to support development,
add --wait-adb and --wait-fastboot options to adjust the timeout.

For TreeHugger testing where other (previous) tests demonstrate
framework or screen regressions, it _may_ be advised to switch to the
--no-wait-screen option so that we do not register a false signal.
It should be noted that some of the past issues with overlayfs and
adb remount could introduce boot up, framework or screen regressions,
so it is advised to not use the option if that interlocking logic can
not be set up.
