llvm_tools: setup_for_workon to look in toolchains-overlay

At present, setup_for_workon.py's --package flag assumes that
the only location where we have toolchain-packages is
chromiumos-overlay. However, we actually have a number of packages,
cross-compilation packages, in toolchains-overlay. For example:

* cross-aarch64-cros-linux-gnu/compiler-rt

When we try emerging these packages without setup_for_workon.py on
that specific cross-* package, we get a missing patch stamp error.
You can use the --ebuild-dir directly to get around this, but this
is somewhat counter-intuitive.

The simplest fix for the issue is to have setup_for_workon.py's
--package flag understand that toolchains-overlay exists.

TEST=py/bin/llvm_tools/setup_for_workon.py \
     --checkout m/main \
     --clean-llvm \
     --package cross-aarch64-cros-linux-gnu/compiler-rt \
     && cros workon --host start \
        cross-aarch64-cros-linux-gnu/compiler-rt
     && sudo emerge cross-aarch64-cros-linux-gnu/compiler-rt
