bitbake: toaster: Check whether buildrequest exists before using it

Builds initiated from the command line don't have a buildrequest
associated with them. The build.buildrequest association is
only added if a build is triggered from toaster.

Some of the code for displaying the status of a build refers
to build.buildrequest without checking whether it has been set,
which causes an error to be thrown.

Add a guard to check whether the buildrequest has been set.
