[Mesa-stable] [PATCH] build: fix out-of-tree builds in gallium/auxiliary

[Ross Burton]

The rules were writing files to e.g. util/u_indices_gen.py, but in an
out-of-tree build this directory doesn't exist in the build directory.  So,
create the directories just in case.

NOTE: This is a candidate for the stable branches.
