build.py: add single-quotes around already-expanded directory name

If the computed name of a directory contains an undefined variable
reference, bitbake dutifully creates a directory with a name that has
${...} in it. However, the actual task script created then tries to cd
to that directory, and the cd command fails, because no such directory
exists -- because the shell has helpfully removed the ${...} which did
not match any actual variables.

Since we want the name to be used exactly-as-is, add single quotes around
the name so this doesn't cause strange failures running tasks, which
allows us to progress past such failures and get to a point where they
can be diagnosed.

bitbake: cooker, toaster: mark interrupted builds as failed

This patch changes bitbake to log an error to the
command line when the build is interrupted via Ctrl-C.

This is needed to inform the user that not all tasks
required for the build have been executed, and
the build is not complete.

Internally, the Bitbake server will return a CommandFailed
event that will be logged by Toaster as build failure.
