[PATCH 2/2] git submodule: Fix adding of submodules at paths with ./

[Michael J Gruber <git@drmicha.warpmail.net>]

Make 'git submodule add' strip './' from 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.
