Following the pattern of other architectures, make __sys_vfork the main
symbol and _vfork and vfork weak aliases. This avoids the need to
special case vfork in the generated list of symbols.

These provide standard APIs, but are implemented using another system
call (e.g., pipe implemented in terms of pipe2) or are interposed by the
threading library to support cancelation.
After discussion with kib (see D44111), I've concluded that it is
better to keep most public interfaces in libc with as little
as possible in libsys.

This file is functionally identical to the stub generated by
Makefile.sys once the MD version is removed.

Historically we exposed _getlogin as a private symbol on a per-arch basis
(except on aarch64 and riscv) for no obvious reason. We now need to
expose it for libc's use so remove the special case from
makesyscalls.lua and expose it in the generated syscalls.map.

libc/<arch>/sys/Makefile.inc -> libsys/<arch>/Makefile.sys.
Require that libsys/<arch>/Makefile.sys exist. At least for current
archtiectures, it's not possible for an architecture to not have and MD
syscall bits.
powerpcspe/Makefile.sys's structure means it had to be modified when moved
so rename detection won't work, but it has trivial contents so the
history is unimportant.

Remove core system call implementations and documentation to lib/libsys
and lib/libsys/<arch> from lib/libc/sys and lib/libc/<arch>/<sys>.
Update paths to allow libc to find them in their new home.
