dropbear: add help text about key creation



Commit e7d04dd2 replaced /etc/dropbear with a symlink to /var/run and
updated the start scripts to replace it with a real directory, so the
keys would be persistent. However, it turns out that this is pretty
confusing even for expert users, who don't know how to make the keys
really persistent now.

Update the help text explaining what the issue is, and telling the user
to replace the /etc/dropbear symlink with a symlink to a persistent
directory. Also mention the possiblity of unionfs.

	  A small SSH 2 server designed for small memory environments.

	  Note that dropbear requires a per-device unique host key. The
	  key will be generated when dropbear starts, but it is not
	  persistent over reboot (if you have a read-only rootfs) or
	  upgrade (if you have a read-write rootfs). To make the key
	  persistent, replace /etc/dropbear with a symlink to a
	  directory on a persistent, writeable filesystem.
	  Alternatively, mount a persistent unionfs over your root
	  filesystem.
