As of Go 1.21 syscall.Setrlimit and syscall.prlimit can affect
starting a new process, by restoring the original NOFILE rlimit.
That is recorded locally in the syscall package, so just always
call the syscall functions.

On Solaris, AIX, and zOS, the req argument of ioctl() is a signed int,
not an unsigned long like on other platforms, which means many constants
are negative, causing friction when passing them to a uint argument.
Correct the signature of these functions to pass the req argument as
signed, just like libc.

Fixes golang/go#59030.

The setattrlist() function can be used to mutate the attributes of files through a single call. For example, one can perform a chmod(), chown(), chflags(), [...] all at once.

This change also adds bindings for the UF_* and SF_* flags that are accepted by chflags(). This makes it possible to use setattrlist() to perform the equivalent of lchflags(), for which we currently have no binding.
