DevelopmentSettings: Add an opt-out for recovery updater

 * Some devices should not have this option,
    for instance all Sony devices supported on CyanogenMod
    already include the ROM's recovery inside the ramdisk
    and provide their own init_sony boot selection

 * Makes sure a user did not enable the option
    on old installations by disabling it if needed

 * Disable the recovery updater through the new overlay

 * Prevent recovery updater related features to run, and
    pass an additional context argument from BootReceiver
    to initializeUpdateRecoveryOption to access resources

 * Similar to the original CM 11.0 commit by Dan Pasanen
