classes: fsl-kernel-localversion: fix usage with devtool

Make fsl-kernel-localversion devtool-compatible, avoiding to depend on
${WORKDIR}/defconfig to be present. Two approaches are taken:

- for recipes inheriting kernel-yocto, LINUX_VERSION_EXTENSION is set to
  LOCALVERSION; in this way, the do_kernel_configme task will use it to
  set CONFIG_LOCALVERSION once the .config file is generated;

- for recipes not inheriting kernel-yocto, CONFIG_LOCALVERSION is simply
  appended to the .config file contained inside the build directory.

The do_kernel_localversion is being made executed after do_kernel_configme
rather than do_kernel_metadata; in this way, modifications are applied
after the config-by-fragments step has already been performed.
