futility/cmd_gbb_utility.c: Allow OR'ing new GBB flags
It maybe the case that the caller wishes to not clobber
the current flags set and merely just OR on the new bits.
BUG=b:270074866
TEST=```
# futility gbb --flash --get --flags
# futility gbb --flash --set --flags=(+|-)0x1
# futility gbb --flash --get --flags
as expected.
```
