sync-all: delete dead code calling gitInitSubmodules

When running './sync-all get', 'git submodule init' has to be (and is
always) executed, since .gitmodules might contain new submodules (see
commit c3db2b). As a result, after cloning the ghc repo and running the
initial './sync-all get', .git/config will always contain some submodule
sections. Therefore it is not needed to check for this on every
subsequent get or pull, and this code can be deleted.
