[PATCH] git-submodule: fix expansion of depth for cmd_update

From: Jacob Keller <redacted>

The depth variable already contains "--depth=", so expanding it with an
additional --depth when invoking the update-clone git submodule--helper
is incorrect.

I'm *reasonably* sure this is correct, but I am not sure how to test it.
It's possible that it expands to "--depth --depth=N" and somehow this gets
handled properly?
