autobuild: change binary for dependency check

Previously identify tool was always compiled into
SPDK, but now there is a flag to disable compilation of
examples. Next patch in series will disable compilation of
examples on some jobs to speed up the test time.

Switch to binary that is always compiled, like spdk_tgt.
