tools/nolibc/unistd: add syscall()
syscall() is used by "normal" libcs to allow users to directly call
syscalls.
By having the same syntax inside nolibc users can more easily write code
that works with different libcs.
The macro logic is adapted from systemtaps STAP_PROBEV() macro that is
released in the public domain / CC0.
