submodule: simplify memory handling in config parsing
We keep a strbuf for the name of the submodule, even though we only ever add one string to it. Let's just use xmemdupz instead, which is slightly more efficient and makes it easier to follow what is going on. Unfortunately, we still end up having to deal with some memory ownership issues in some code branches, as we have to allocate the string in order to do a string list lookup, and then only sometimes want to hand ownership of that string over to the string_list. Still, making that explicit in the code (as opposed to sometimes detaching the strbuf, and then always releasing it) makes it a little more obvious what is going on.
