bitbake: runqueue.py: always emit bb.event.DepTreeGenerated

The data included in the event is useful for implementing a pre-build
check that warns about unexpected components, for example because of
an incorrect configuration or changed dependencies.

Such a check can be done in a .bbclass that gets inherited
globally. But in contrast to a UI, such a class cannot request that
the event shall be emitted, and thus the event has to be emitted
whether there is a consumer or not.

This was done conditionally earlier out of concerns about the
performance impact. But now events are handled more efficiently, so
that concern no longer seems valid: in some simple testing (admittedly
on a fast build workstation), the two lines (generating the data and
emitting the event with it) only took about 0.05 seconds (measured
with timeit). That was for a build with roughly 500 recipes (from
pn-buildlist aka depgraph['pn']), triggered via the command line. That
was even with a consumer of the data active and doing some work, so it
should be even faster when there is no consumer.
