media_build broken by missing vb2.h

Hi.

i just tried to compile media_build as of today but it doesn't work very well.

after a while it errors with:
media_build/v4l/vb2-trace.c:4:30: fatal error: trace/events/vb2.h: No such file or directory

i assume something is broken in the git repo and i just have to wait? or did i do something wrong?
