Revert gps.omap4.so and sirfgps.conf updates.

These files were aimed at maguro and seem to be causing problems with
toro. The previous gps.omap4.so was from 4.0.4, so I updated that to
match the 4.1.1 OTA as well.

I saw others posting about this on XDA and delved into it a bit further. Looks like the gps.omap4.so has always been a much smaller/different file for the GSM variant. I have been testing this since last night and my GPS locks have been much quicker and more consistent. I have also not had any kernel wakelock issues so far in my testing, short though it has been. Kernel wakelocks were rather severe before with a gps-lock being almost constant.
