meta-phosphor: Opt out of new systemd configs

Opt out of new systemd meson config options by default.  This keeps our
systemd configuration as minimal as possible by default, and makes an
explicit statement about what is supported by meta-phosphor and what is
not.

(From meta-phosphor rev: 1ea62b5ba89e07d0ee0ac8afecbe124ccc2909f6)
