meta-google: ipmi-fru-sh: Correct checksum calculation

Blocks reads, whos values are greated than 128, will be formated as
negative integers, causing cascading errors in the checksum calculation.

Format using unsigned specifier instead to prevent this.

Tested:
Before:
```
dd if=/sys/bus/i2c/devices/13-0050/eeprom bs=1 count=8 skip=8 | \
    hexdump -v -e '1/1 "%d "'
1 1 32 36 -107 47 -115 -121
```
After:
```
dd if=/sys/bus/i2c/devices/13-0050/eeprom bs=1 count=8 skip=8 | \
    hexdump -v -e '1/1 "%u "'
1 1 32 36 149 47 141 135
```
