linux-yocto: introduce 5.0 versioned recipe

Introducing the 5.0 linux-yocto reference kernel, which will become
the "latest" kernel as part of the spring yocto release.

qemu* has been built and sanity tested against this kernel, and it
is suitable to become the default build for the emulated references.

Some minor configuration cleanup was performed, but otherwise, things
are very similar to the 4.19 kernel config:

  7fdb966db86 (HEAD -> yocto-5.0) aufs4: kbuild patch
  c76b027a8b2 iosched: remove configs for removed legacy io schedules
  5d1f8102244 netfilter: drop removed config options
  8ff16f508f5 kernel-yocto: 5.0 kernel prep

Feature wise, this is a match for 4.19, with yaffs2 and aufs4 being
kept around for another release. Aufs is scheduled for removal in
the fall release.
