submodule: also validate Windows-separated paths for validity
Otherwise we would also admit `..\..\foo\bar` as a valid path and fail to
protect Windows users.
Ideally we would check for both separators without the need for the copied
string, but this'll get us over the RCE.

submodule: ignore submodules which include path traversal in their name
If the we decide that the "name" of the submodule (i.e. its path inside
`.git/modules/`) is trying to escape that directory or otherwise trick us, we
ignore the configuration for that submodule.
This leaves us with a half-configured submodule when looking it up by path, but
it's the same result as if the configuration really were missing.
The name check is potentially more strict than it needs to be, but it lets us
re-use the check we're doing for the checkout. The function that encapsulates
this logic is ready to be exported but we don't want to do that in a security
release so it remains internal for now.

submodule: add a failing test for a submodule escaping .git/modules
We should pretend such submdules do not exist as it can lead to RCE.
