[Buildroot] [git commit] package/systemd: check BR2_TARGET_GENERIC_GETTY

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=2a8ceecd80baf21df509c96d0cbc9a1b39cd7d4b
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Do not create a [serial-]getty link if BR2_TARGET_GENERIC_GETTY is not set.
Might be useful for custom setups (rootfs overlay).

[Peter: use BR2_TARGET_GENERIC_GETTY_PORT to match the code below]
