bitbake: toaster: Rationalise mimetype guessing to fix artifact downloads

Artifact download links were broken because the function to
get the mimetype for the artifact was incorrectly using the
underlying mimetype library. The function was also attached
to the build environment controller, which was unnecessary, as
we only support local controllers anyway.

Remove the mimetype getter on the build environment and
use the one in the view code instead. This works correctly
and prevents the download error from occurring.
