On Cygwin, use symbolic ref, not a symbolic link, to express .git/HEAD

H. Peter Anvin says that Samba "promotes" symlinks to hardlinks while
Cygwin itself uses .lnk files to emulate symlinks.  Avoid using symbolic
link for .git/HEAD on Cygwin.

This does not help the symlinks recorded in trees as user data, but
at least we do not use them for our own bookkeeping.
