trace-cmd: Fix build dependencies
After having trace-cmd break because not all proper files are being compiled
when needed, I looked into why the dependencies were not working. I found
that the .foo.d files that were being created required having the full path
of the object file in them. Without that, the dependencies were being
ignored.
By adding "-MT $(bdir)/$*.o", to the dependency creating rules, the full
path would be added to targets for the object files, and this makes the
depencies work again.
