the utsrelease.h is not included in the STAGING_KERNEL_DIR, but in STAGING_KERNEL_BUILDDIR
So, adding a hacky symlink into the source directory fixes the issue for now.
This can be re-evaluated if poky maintainers start shipping such file into another directory or patch module*.bbclass to take account
of this additional dir into *FLAGS
