cannot find value `_UFFDIO_WRITEPROTECT` in this scope

I try to build on Ubuntu 2004, and I've this error during the build of userfaultfd-rs crate:

  error[E0425]: cannot find value `_UFFDIO_WRITEPROTECT` in this scope
  --> src/linux5_7.rs:20:74

   | ------------------------------------------------ similarly named constant `UFFDIO_WRITEPROTECT` defined here

I try several kernel headers versions after 5.7 but none works.

@musitdev I've pushed a fix - mevi doesn't even need those 5.7+ functions anyway. Enjoy!
