[OE-core] [PATCH] kernel-devsrc: add 'make scripts' postinstall

[Ming Liu]

From: Ming Liu <peter.x.liu at external.atlascopco.com>

Run 'make scripts' inside qemu in order to create script binaries that
needed by external modules build on the target.

This 'make scripts' might fail in some cases, for instance, if toolchain or
make command is not installed on the target, but the postinstall should
always succeed, it will not break the package installation so the behaviour
is consistent.

[YOCTO #6630]
