Improve system call wrappers
This change improves copy_file_range(), sendfile(), splice(), openpty(),
closefrom(), close_range(), fadvise() and posix_fadvise() in addition to
writing tests that confirm things like errno and seeking behavior across
platforms. We now less aggressively polyfill behavior with some of these
functions when the platform support isn't available. Please see:

f7c7b949fd Explore comfort level with posix_spawn
Justine says nay for the time being. Only XNU implements this. It's not
clear what ABI XNU is using but it's obviously not the one in the POSIX
documentation link below. Since all platforms implement vfork, it might
be better to empirically gauge the intersection of consensus which will
have better performance than this interface.
