git-svn: disable broken symlink workaround by default

Even though this will break things for some extremely rare repositories
used by broken Windows clients, it's probably not worth enabling this by
default as it has negatively affected many more users than it has helped
from what we've seen so far.

The extremely rare repositories that have broken symlinks in them will be
silently corrupted in import; but users can still reenable this option and
restart the import.
