dbg! on Ipv6Addr should not show leading '0x'

I tried this code:

let ip = Ipv6Addr::new(123, 0, 3, 0, 0, 0, 36, 2);
dbg!(&ip);

I expected to see this happen: It prints 7b:0:3::24:2

Instead, this happened: It prints 0x7b:0x0:0x3::0x24:0x2

@KSXGitHub are you interested in fixing this yourself? I think the relevant code is

rust/library/std/src/net/ip.rs

Line 1614 in f09fb48

fmt::LowerHex::fmt(first, f)?;

@jyn514 Nope, I'm not interested spending half a day compiling this repo.
