Don't clear the caller's existing known_hosts file.

Replace truncate call with touch call to avoid truncating user's
existing known_hosts file.  We don't want the caller's known_hosts
file to be erased when entering a chroot.

This was introduced with commit add9976e45a9 ("enter_chroot: bind mount
~/.ssh/known_hosts")

BUG=None
TEST=Hosts file remains intact after this change
