[OE-core] [rocko][PATCH 2/2] make-mod-scripts: add build requirements for external modules

[Anuj Mittal]

From: Bruce Ashfield <bruce.ashfield at windriver.com>

Newer kernels (4.14/v4.15+) have dependencies for the build of
modules (and hence external modules). Without these dependencies
explicitly in the build chain, you can end up with build failures like:

  work-shared/qemux86/kernel-source/scripts/extract-cert.c:21:25: fatal
  error: openssl/bio.h: No such file or directory
  |  #include <openssl/bio.h>
  |                          ^
  | compilation terminated.
  | make[2]: *** [scripts/extract-cert] Error 1
  | make[1]: *** [scripts] Error 2

To ensure that these headers are in place, and that the scripts use
our build environment flags, we add a dependency on openssl-native
and use oe_make to invoke the build.

Older kernels have no issues with the extra dependency, so there's no
need to make this conditional.

(From OE-Core rev: 916cb2029d3c97bf12ebf03832b9ba980451dbcf)

Fixes [YOCTO #12860]

[Tweaked to have changes in module*.bbclass instead from where
make-mod-scripts was split in sumo]
