ssh_util: handle non-default AuthorizedKeysFile config (#586)
The following commit merged all ssh keys into a default user file
`~/.ssh/authorized_keys` in sshd_config had multiple files configured for
AuthorizedKeysFile:

Multiple file fix for AuthorizedKeysFile config (#60)
This commit ignored the case when sshd_config would have a single file for
AuthorizedKeysFile, but a non default configuration, for example
`~/.ssh/authorized_keys_foobar`. In this case cloud-init would grab all keys
from this file and write a new one, the default `~/.ssh/authorized_keys`
causing the bug.
