Fixed eat not waiting for device if adb server was not started

$(adb get-state) returned unexpected starting server message
causing the if statement to fail. Calling "adb start-server"
beforehand remedies that.

Patch Set 2:
$(adb get-state) returns 'unknown' if Clockwork recovery is running on the device
look for /sbin/recovery and 'pass' the state test
also
adb wait-for-device
will result in endless loop, replace with until loop using with get-state OR 'recovery' tests

Patch Set 3:
fix the initial adb state test, use AND instead of OR

Patch Set 4:
Rebased and prevent "device not found" message from spamming the screen by
redirecting error output to null

envsetup: Make eat restart adbd as root before pushing the recovery command

Without adbd running as root we can't write to /cache/recovery and
eat fails with a permission denied.

Eat: Option to specify directory of zip in recovery mode

It pushes to /mnt/sdcard0, which may be /emmc/ in recovery. Now the user
can specify another path other than /sdcard/ where the zip is

screwd: Fix global selinux policy inclusion

We're adding CM-specific policies to an overlay instead of patching
external/sepolicy, so we need to make sure it's included to prevent
misbehaving systems
