[v2,2/2] kmscon: Add recipe

Provide sane defaults that do not have dependencies, such as
a dummy and terminal session support and basic fbdev support.

kmsconvt@.service must be added separatly or else
do_rootfs fails with the following error:

```
do_rootfs: Postinstall scriptlets of ['kmscon'] 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.
```

Thanks for your submission. This fails to build with TOOLCHAIN = "clang"

Hi Khem!

Thanks for the test! I didn't know about TOOLCHAIN = "clang" and will get
it fixed!

Thanks again!
