scripts/hob: wrapper script to run hob gui with a UI specific config file

This ensures any configuration changes made in the GUI are only set when
using hob.
The default hob.local.conf is generated with a line which adds image_types
to INHERITS so that the GUI can introspect the available FSTYPES.
