openssh: use config snippet instead of file

Config snippets should be used over file overrides since targeted
changes may be required in multiple recipes.

Since the oe-core sshd_config file now includes
/etc/ssh/sshd_config.d/*.conf, the meta-selinux configuration snippet
does not require the following:

* ChallengeResponseAutnetication: Replaced by
  KbdInteractiveAuthentication and set to "no" by default

* Override default of no subsystems: This is already present

* Compression, ClientAliveInterval, and ClientAliveCountMax: No changes
  required due to identical requirements of meta-selinux

Testing process:

* Pulled modified meta-selinux layer into Poky and included openssh

* Built core-image-sato and ran via qemu

* Verified /etc/ssh was as expected with an ssh_config.d directory with
  the new selinux config snippet inside

* Verified system was including selinux config modification by running
  sshd -T
