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.
