git submodule: Fix adding of submodules at paths with ./, .. and //

Browse source 
Make 'git submodule add' normalize the submodule path in the
same way as 'git ls-files' does, so that 'git submodule init' looks up
the information in .gitmodules with the same key under which 'git
submodule add' stores it.

This fixes 4 known breakages.
