[PATCH] builtin/describe.c: ignore untracked changes in submodules

From: Brandon Casey <redacted>

Since 'git describe' does not append -dirty to the version string it
produces when untracked files exist in the working directory of the main
repository, it should not do so for submodules either.

Add --ignore-submodules=untracked to the call to diff-index which is used
to decide whether or not the '-dirty' string is necessary.
