bitbake: toaster: checksettings call django's loaddata instead of custom command

Call django's inbuilt loaddata command to load the appropriate fixtures.
We also attempt to load a fixture called "custom" and fail silently if
we don't have one. This is where initial customisations can be done to
load particular settings or data into Toaster (for example layers or
default values for variables)

Make sure the value for TEMPLATECONF is available to checksettings so
that we can have a go a working out which default data to load.
