Add support for NetBSD 9.0 and newer versions of interceptors
operating on struct statvfs: fstatvfs, fstatvfs1, getmntinfo,
getvfsstat, statvfs, statvfs1.

The default promoted interceptors are for NetBSD 9.99.26. Older
ones (currently 9.0) are kept in a new NetBSD specific file:
/sanitizer_common_interceptors_netbsd_compat.inc. This file
defines compat interceptors and mangles `INIT_*` macros,
concatenating the current interceptors and the compat ones.
This redefinition is not elegant, but it avoids preprocessor madness.

Define struct_statvfs90_sz for the compat purposes.
