[aur-general] Rename request: fedora-icon-theme -> echo-icon-theme

[Jerome Leclanche]

https://aur.archlinux.org/packages/fedora-icon-theme/

I cleaned up the package however it still needs renaming to echo-icon-theme.

Git version is properly named:
https://aur.archlinux.org/packages/echo-icon-theme-git/
