payloads: Add target to download depthcharge source

This lets the user manually download the source for a payload before
running the full make. This can be used to apply patches against a
specific version, or to download the payload for offline use later.
This can also be used as a part of the build system to download the
payloads for testing before the coreboot build is started (and can no
longer access the internet).

If the payload is currently specified as a part of the .config, the tag
will be checked out after the source tree is fetched. Otherwise the
source for depthcharge will be downloaded and no tag will be checked
out.

If this seems useful, I can add it to the rest of the payloads, and add
a download-all-payloads target or something as well.
