Edited extract-files.sh so that build will continue.

In Line 269 of extract-files.sh, it looks for galaxys2common/proprietary/hwcomposer/lib/libfimc.so

There is no hwcomposer/lib/libfimc.so file let alone the directory hwcomposer or subdirectory lib.

I had the "hwcomposer/lib/" removed so that build will proceed.  Unless there is another libfimc.so that extracts to hwcomposer/lib this is the only work around I could find.  I am using an i777 so I would not know if the i9100 will extract said file to said directory.

For reference: the error I get on build is:

make: *** No rule to make target `vendor/samsung/galaxys2-common/proprietary/hwcomposer/lib/libfimc.so', needed by `out/target/product/i777/obj/lib/libfimc.so'.  Stop.

Thanks guys for CM 9 on my i777.
