getUserInfo
The problem initially starts here, when using std.process.getUserInfo:

Expected Behavior
Expected to compile given the name parameter, although this is unlikely to be possible given that the underlying issue is an Io interface not being propagated properly. That said, expected to compile given a fix to expect both an Io and name parameter.

### Steps to Reproduce and Observed Behavior
## `getUserInfo`
The problem initially starts here, when using `std.process.getUserInfo`:
```zig
const std = @import("std");
pub fn main() !void {
const name:[]const u8 = "root";
const userinfo = try std.process.getUserInfo(name);
std.debug.print("hello {d}\n", .{userinfo.uid});
}
```
