std.os.getrusage: add C extern fn and reserved field

* add reserved field to match musl struct definition so that
   it will work with musl libc.
 * add libc getrusage so that it will work with libc

what's not done in this branch is:
 * test coverage. See #1629, which should also aim to provide
   general test coverage for the std lib.
 * rusage struct bits for non-linux operating systems
