kbd: avoid vlock conflict with busybox

busybox as well as vlock utility from meta-oe provides vlock utility
which can conflict when with kbd if pam is a enabled distro_feature

Fixes image build errors

update-alternatives: Error: not linking <rootfs>/usr/bin/vlock to /bin/busybox.suid since <rootfs>/usr/bin/vlock exists and is not a link

ERROR: yoe-qt5-wayland-image-1.0-r0 do_rootfs: Postinstall scriptlets of ['busybox'] have failed. If the intention is to defer them to first boot,
then please place them into pkg_postinst_ontarget_${PN} ().
Deferring to first boot via 'exit 1' is no longer supported.

The vlock doesn't exist if PAM isn't enabled.
