libc: Do not use the heavy variadic syscall() function for wrappers
...
That function is meant more for user programs, and should still be rarely used, since it's not portable.
Instead, we already know the number of arguments. We just call __lc_fast_syscallN, which also sets errno.

This function is a Luna alternative to fork() and exec().
Why? Simply because I can't figure out for the life of me how to implement a working fork().
So meanwhile, we have spawn() as a replacement. exec() still exists, though.
