This is also similar with how we handle seccomp in linux_prctl().

I have added linux_kplatform for consistency with linux_platform which is placed in to vdso to avoid excess copyout it on stack for AT_PLATFORM at exec time. This is the first stage of Linuxulator's vdso revision.

Note that AT_HWCAP2 we pass to Linux binaries is always 0, instead of being equal to 'cpu_feature2'. This matches what I've observed under Ubuntu Focal VM.
