VxWorks std does not build

[Noratrieb]

Since 2025-05-15, vxworks std does not build: https://does-it-build.noratrieb.dev/target?target=aarch64-wrs-vxworks

https://does-it-build.noratrieb.dev/build?nightly=2025-07-04&target=aarch64-wrs-vxworks&mode=miri-std there's a type error.

rust-lang/libc#4407 added these values but they do not seem to have the types expected by std.
