8b0ab33247 compat/posix: introduce writev(3p) wrapper 
In a subsequent commit we're going to add the first caller to
writev(3p). Introduce a compatibility wrapper for this syscall that we
can use on systems that don't have this syscall.

The syscall exists on modern Unixes like Linux and macOS, and seemingly
even for NonStop according to [1]. It doesn't seem to exist on Windows
though.

This reverts commit 3b9b2c2a29a1d529ca9884fa0a6529f6e2496abe; let's
not use writev() for now.
