[patch] Update textproc/git-delta to 0.8.3

[Michael-John Turner <mj%mjturner.net@localhost>]

[Resending with a link to the patch rather than an attachment]

Hi all,

Please find below a link to patch to update textproc/git-delta from 0.4.4
to 0.8.3. Tested and working fine on NetBSD and macOS.

http://dl.rsx11.net/misc/git-delta-0.8.3.patch 

I've removed the patches as they're no longer needed and moved the
dependencies into cargo-depends.mk, as is the current convention for Rust
packages.

Cheers, MJ
