[Buildroot] [git commit branch/2017.02.x] system: only expose getty options for busybox and sysvinit

commit: https://git.buildroot.net/buildroot/commit/?id=d40ba85e00cc819f4dcb9da8fbbfd151877d462b
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.02.x

Only busybox and sysvinit handle the BR2_TARGET_GENERIC_GETTY_TERM and
BR2_TARGET_GENERIC_GETTY_OPTIONS options; the other init systems do
not.

So, protect those options behind appropriate dependencies on busybox
or sysvinit.

Fixes #10301.
