bitbake: toaster: change startup parameter passing to avoid race

We avoid a race between the setting the TOASTER_BRBE variable
and reading the variable in toaster ui by supplying the variable
at server startup time through the toaster.conf post-read file.

Additional small changes are included, including marking the
build request with the environment id of where the build took place.
