Norman Feske d6a312f438 tool/builddir: pass --ccache to run tool
With this patch, the build directory's CCACHE configuration is applied
to the building of depot archives when using the --depot-auto-update
feature.

Note that this is effective only when resetting the hash files before
building so that each depot-auto-update results in the same-named
versions. Otherwise, the include paths (that include the version name as
part of the path) make cache hits impossible.
