The idea of __stat_fixup is that it would patch a broken struct layout
after a successful stat-family call, not make a new syscall. For a new
syscall it would have to be separate workaround code in each variant
(stat, lstat, fstat, fstatat) to do the appropriate workaround for
each. This is a completely different scope.

I don't think there's any viable way to support kernels that old even
partially without backporting some essential features.
