linux-libc-headers: multilib_header asm/kvm_para.h and asm/bpf_perf_event.h
When building SDK via populate_sdk for qemuarm64 with multilib
enabled, we would have conflict about bits/floatn.h at populate_sdk
time.
file /usr/include/asm/bpf_perf_event.h conflicts between attempted installs of lib32-linux-libc-headers-dev-4.15.7-r0.armv7vehf_vfp and linux-libc-headers-dev-4.15.7-r0.aarch64
file /usr/include/asm/kvm_para.h conflicts between attempted installs of lib32-linux-libc-headers-dev-4.15.7-r0.armv7vehf_vfp and linux-libc-headers-dev-4.15.7-r0.aarch64
Apply oe_multilib_header on these header files to fix the problem.
