Phil Elwell 797299e16f pps: Compatibility hack should be X86-specific ...

As of [1], using PPS_FETCH on a 64-bit ARM kernel with a 32-bit userland
is broken, returning a timeout. This is because the requested 4-byte
alignment for struct pps_ktime_compat (illegal on arm64) results in the
timeout flags field being uninitialised.

Make the hack specific to X86_64 builds with CONFIG_COMPAT defined.

    ioctl_compat")
