git-svn: ensure we're at the top-level and can access $GIT_DIR

If we are run inside a subdirectory of a working tree, we'll
chdir to the top first before touching anything.  This also
prevents the accidental creation of .git directories inside
subdirectories since they need metadata.

Noticed by maio on #git
