Port lpm.rc to the Android system

With Android 5.0.0 changes, the original way of booting into charger mode
does not work anymore. Port lpm.rc to the Android method.

Note: This still requires the android system core init patch that
reads the charging mode kernel bootarg (BOARD_CHARGING_MODE_BOOTING_LPM).
Custom toolchain flags
Modify lpm.rc to run under the lpm-init action
overlay: Add power menu options
