pengus77 sdcard/lgdrm stuff via customreleasetool

Ivan Cerrato <ivan@cerrato.biz> added the sdcard and lgdrm.img check to
android_build - this commit avoids a forked build by applying these patches
via a custom releasetool.

update brightness and light sensor sysfs paths
ICS uses different default paths than GB. Using the old ones caused some weird
behaviour like the brightness being to low after unlocking.
