qemu-v8: Linux kernel and Buildroot updates

Linux kernel: Update Linux kernel to point to the most current OP-TEE
commit (based on v5.1).

Buildroot: Update to the commit in Buildroot just before optee_client
was officially introduced in Buildroot. There seems to be a build
regression when using build.git and Buildroot versions where
optee_client.git are officially merged.
