syscalls: normalize _exit(2) declerations

exit(3) is implemented by the runtime and performs a number of shutdown
actions before ultimately calling _exit(2) to terminate the program. We
historically named the syscall table entry `exit` rather than `_exit`,
but this requires special handling in libc/libsys to cause the `_exit`
symbol to exist while implementing `exit` in libc.

Declare the syscall as `_exit` and flow that through the system.

Because syscall(SYS_exit, code) is fairly widely used, allow a
configured extra line in syscall.h to define SYS_exit to SYS__exit.

I've found no external uses of __sys_exit() so I've not bothered to
create a compatability version of this private symbol.

This declares an API for libsys which currently consists of

implementation resides in a generated _libsys.h which ensures that all
system call stub declarations match syscalls.master.

libsys: generate private symbol map

We now export all _ and __sys_ prefixed syscalls stubs from libc and
