[PATCH] cg-seek should not complain if run twice

[Pavel Roskin <proski@gnu.org>]

cg-seek complains if run without arguments in a non-seeked repository:

rm: cannot remove `.git/refs/heads/cg-seek-point': No such file or directory
rm: cannot remove `.git/head-name': No such file or directory

In fact, it's OK for those files not to exist, so they should be removed
silently.
