gitmodules: Fix 3rdparty updates

Commit 039223a: gitmodules: Ignore 3rdparty in "diff family"
changed the behavior of our 3rdparty repository and disallowed
updates to the checked out hash. Instead of "ignore=all" we
want "ignore=dirty" to ignore local changes but allow changing
to the HEAD of the 3rdparty repo.
