Sprinkled examples of layers that use ":append" without a leading space

  Recently, I noticed the occasional example in some layers where
there *appears* to be a missing leading space when using the ":append"
operator.

  As a single example in the meta-virualization layer:

https://git.yoctoproject.org/meta-virtualization/tree/recipes-core/kata-containers

  kata-agent_git.bb:RDEPENDS:${PN}-dev:append = "bash"
  kata-proxy_git.bb:RDEPENDS:${PN}-dev:append = "bash"
  kata-runtime_git.bb:RDEPENDS:${PN}-dev:append = "bash"
  kata-shim_git.bb:RDEPENDS:${PN}-dev:append = "bash"

Just thought I'd point it out so layer maintainers might do a quick
check on their layers.
