Sasha Levin 352665c558 tools/dma: fix building from the top level with O= ...

"make O=<dir> tools/dma" fails:

  Makefile:27: /tools/build/Makefile.include: No such file or directory

tools/Makefile clears srctree, and the dma Makefile only works it out
again when building_out_of_srctree is not set, which the top-level
Makefile sets for O= builds.

Also work out srctree when it is empty, as tools/bpf/Makefile does
since commit a89b2cbf71 ("tools, bpf: Fix build for 'make -s
tools/bpf O=<dir>'").

Fixes: f74ee32963 ("tools/dma: move dma_map_benchmark from selftests to tools/dma")
