Subject: recovery: change the way of rebooting when using power key combo

The power key combo allow to reboot from recovery mode by pressing
power button 7 times in a row. It calls directly the function
android_reboot() and lead to permission denial errors because of SE
Linux rules enforcement.
The right way to reboot from recovery is to set the property
"sys.powerctl" and let init handle it.
