Cancel builds when cli is interrupted

If a bitbake build is running on the command line and is interrupted (e.g. by Ctrl-c), capture the interrupt and shut down the bitbake server. Also set the outcome to CANCELLED so the build displays correctly in the Toaster UI.

The following changes since commit c8ea873d9883f8cdabb6ccadd31bd9967a0f0111:
