[PATCH] bltin: fix timescmd with C23

[Sam James <sam@xxxxxxxxxx>]

With C23 and LTO, we get the following warning (or error if promoted to such):
```
src/builtins.c:28:5: error: type of ‘timescmd’ does not match original declaration [-Werror=lto-type-mismatch]
   28 | int timescmd(int, char **);
      |     ^
src/bltin/times.c:15:5: note: type mismatch in parameter 1
src/bltin/times.c:15:5: note: type ‘void’ should match type ‘int’
```

Make the two consistent. This didn't show up before because pre-C23
had unprototyped functions.
