Modify dev_debug_vboot for better usefulness

Modify dev_debug_vboot for better usefulness

* Display only the synopsis on stdout
* Keep a verbose log of all activity in the scratch directory.
* Add more checks
* Providing a directory argument will use the images found there instead of
  trying to extract them from the system (for use on host machines).

Get a root shell and run "dev_debug_vboot". You should see nicer output.

Would be good to add TPM version dump, as since introduction of the
TPM support it became one of of the likely reasons for boot problems.
