Subject: Define _STAT_VER & _MKNOD_VER locally (dropped in glibc 2.33)

In glibc 2.33, they've removed the _STAT_VER and _MKNOD_VER definitions
from public headers. They have no plans to add these back so checkinstall
needs to attempt its own definitions. There is some protection as if they
were wrong and there was a mismatch, we'd get an error at runtime.

Removed in upstream glibc:
