bitbake: toaster: Write logs to BUILDDIR/toaster_logs

Fixes "2efb14648 toaster: Monitoring - implement Django logging system" when
running in a container.

When running in a container, the previous approach of using BASE_DIR
is not a writable path. Also, we really do not want to be writing logs into
the source tree, as the BASE_DIR was resolving to bitbake/lib/toaster/logs

Since Toaster is only ever running in an environment where oe-init-buildenv
or similar has been sourced, we should instead write the logs to BUILDDIR.

Using BUILDDIR to logs make path writable but django-log-viewer does'nt manage
to write logs using an absolute path as BUILDDIR, where the existing toaster_ui.log
was already being written.

Also drop the /logs/ directory, as it has not been created which also breaks
in a container environment

To handle the constraints linked to django-log-viewer and /logs/, we've updated
bitbake/bin/toaster to create a toaster_logs/ directory in BUILDDIR if it doesn't exist,
when toaster starts up.

Also manage to set BUILDDIR/toaster_logs/ as default location for toaster logs.
