[oe] [meta-oe][PATCH 1/3] kernel.bbclass: fix external module building

[Denis 'GNUtoo' Carikli]

Without that fix we have the following while compiling compat-wireless.
  include/linux/mmzone.h:18:30: fatal error: generated/bounds.h: No such file or directory

Note that the compat-wireless recipe will be added in another commit.
