[OE-core] [PATCH v3] init-live: default to initrd shell if image isn't found

From: Alexandru DAMIAN <alexandru.damian at intel.com>
Adds "debugshell" command line parameter for live/install images.
If the init live fails to find and mount a root-fs image,
dumps to a shell after timeout so that the developer can figure
what's wrong.
Timeout defaults to 30 seconds, but it can be changed as param
argument.
Prior art in Ubuntu. Also, leaving a system stale isn't good form.
