cli_classic.c: Allow ctrl of behaviour with WO and RO regions

Add two force flags to the flashrom CLI frontend,
  --force-skip-nonreadable - skip reading non-readbale regions without failure,
  --force-skip-nonwritable - skip writing non-writable regions without failure.

Each flag allows the user to finely control the behaviour of
flashrom read and write operations when flashrom encounters a
known permission problem. This can be useful in cases such as
wanting to write a pre-padded BIOS image across flash where locked
regions just wish to be left untouched without the need to craft a
custom layout file for each case. Alternatively, to read a copy of
flash complete with padding for regions that are known not to be
readable at runtime however the user does not know the layout of
flash or just wishes to have a padded binary read back.
