pmb: add -f (force) parameter to bootimg_analyze

Browse source 
We are analyzing the `boot.img` with `file` before we send it to
`unpackbootimg`. File does not recognize all kinds of `boot.img` files,
which `unpackbootimg` can extract, so we need a way to skip this check.

Details:
* Add `-f` parameter, continues extraction with a warning if the file
  seems to be invalid
* Tell the user that `-f` can be used if the `boot.img` is invalid and
  it's not specified
* Consistent spelling of `boot.img` instead of `bootimg` in messages

Fixes #1608
