[PATCH] kernel: remove unused 'etc' directory

[Mark Asselstine <mark.asselstine@windriver.com>]

Along with checks to remove empty modprobe.d and modules-load.d
directories we can add a similar check and removal of the etc
directory. This will avoid warnings by the sanity checker.

There is some concern that removing this directory could cause issues
if folks are adding to etc in a bbappend and not checking for and
creating this directory. I don't believe this is an issue as if you
want to add something to etc it should be done as part of a
populate_packages_prepend or earlier since there are sanity checks run
as part of populate_packages, so the removal here is being done at the
latest possible point in the process (populate_packages_prepend in a
bbappend will run before the populate_packages_prepend in
kernel.bbclass).
