futility/flashrom_drv: Add new skip perm flags to read path

flashrom now respects region permissions rather than ignoring
exit codes. While downstreaming this support we require these
flags to be set to ensure no change in behavior for futility.

It turns out chromeos-firmware-updater will fail on the read
path with,
```
[..]
read_flash: cannot read inside Management Engine region
(0x001000..0x1fffff).
Read operation failed!
ERROR: do_update: Cannot load system active firmware.
```
without skipping regions that cannot actually be read.
