Revert "std.fmt: require specifier for unwrapping ?T and E!T."

This reverts commit 7cbd586ace46a8e8cebab660ebca3cfc049305d9.

This is causing a fail to build from source:

```
./lib/std/fmt.zig:492:17: error: cannot format optional without a specifier (i.e. {?} or {any})
                @compileError("cannot format optional without a specifier (i.e. {?} or {any})");
                ^
./src/link/MachO/Atom.zig:544:26: note: called from here
                log.debug("  RELA({s}) @ {x} => %{d} in object({d})", .{
                         ^
```

I looked at the code to fix it but none of those args are optionals.
