Samsung-i9003: Correcting problems with kernel modules

In the kernel from the linux-samsung-i9003 package, the modules wl12xx, mac80211 and cfg80211.ko are assembled as modules, but due to the lack of the command make modules_install in APKBUILD, these modules are not included in the finished package. Because of this, it was impossible to launch WI-FI on Samsung-i9003. I added the necessary commands to APKBUILD to fix this problem.
