Subject: [PATCH] shared: compare submodules case-insensitively

If module-link is read from a repository's Git config, then our callback
is invoked with the name converted to lower case (as all Git config keys
are).  This means we can never match a submodule containing uppercase
characters against such a module-link.

Compare submodule names case-insensitively to avoid this problem.  This
may break a use case where two submodules differ only in case, but that
is much less likely than a submodule name using uppercase characters.
