Temporarily Revert "[compiler-rt] [netbsd] Add support for versioned statvfs interceptors"

as it's failing the netbsd specific linter parts of the sanitizer linter:

llvm-project/compiler-rt/lib/sanitizer_common/sanitizer_common_interceptors_netbsd_compat.inc:23:  Lines should be <= 80 characters long  [whitespace/line_length]
llvm-project/compiler-rt/lib/sanitizer_common/sanitizer_platform_limits_netbsd.cpp:2450:  Do not use variable-length arrays.  Use an appropriately named ('k' followed by CamelCase) compile-time constant for the size.

This reverts commit 78f714f8.
