Fix blobs

I was not able to compile vanilla cyanogenmod for my Samsung Galaxy Ace (cooper, GT-S5830).

Main problems were with extract-files.sh.

First, the file "bdata.SD31.bin.04" gets copied as "bdata.SD31.bin.01" thus making the build faild (bad make target).

Second, it installed "libcamera.so" as "liblilgcamera.so". CM would thus not boot (stucked at "ANDROID" written in center of black screen). logcat revealed the missing libcamera.so.

I still had issues with wifi (logcat revealed "E/WifiService(  260): Failed to load Wi-Fi driver"). It was fixed by using CM's athwlan.bin.z77 and ar6000.ko which had a different md5sum as the one provided by the stock firmware.
