Updated reference to AUR submodules

[e-dong]

Added @Proryanator as co-maintainer to AUR packages!

• https://aur.archlinux.org/packages/encoder-benchmark-git
• https://aur.archlinux.org/packages/encoder-benchmark

Please vote for the package, since a popular package has a better chance of entering the Arch's extra repo. This is where Arch devs help us maintain the package!
