stock GT-I9305 16G PIT: remove unknown data
With the 16G.pit file we have the following information:
- Device variant: GT-I9305
- eMMC size: 16G
- Data at 0xA6C:
0000 0A4C: 72 65 6D 61 69 6E 65 64 00 00 00 00 00 00 00 00 remained ........

With another PIT we have differences starting at 0x85C:
- Device variant: GT-I9305
- eMMC size: 16G
- ro.bootloader: I9305XXSFQD1
- Data at 0xA6C:

I've no idea what that data is, so it's better to remove it as it may
contain data that is either privacy or security sensitive or data that
we may not be able to redistribute.
The comparison was done with vbindiff and stripping the data was
achieved with the following commands:
$ dd if=16G.pit of=new.pit count=2668 bs=1
$ mv new.pit 16G.pit
The output of 'heimdall print-pit --file' is exactly the same between the
old 16G.pit, the new one, and all other PITs mentioned above.
Once stripped, all the PITs were identical bit by bit. This was verified
with the cmp command.
