trace: move setting of group name into Makefiles
Having tracetool.py figure out the right group name from just the input filename is not practical when considering the different build vs src path combinations. Instead simply take the group name as a command line arg from the Makefile, which can trivially provide the right name. Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Daniel P.
