bug#49371: Removing the broken ‘corrode’ package

[Tobias Geerinckx-Rice]

Guix,

Cool hack though it was, I propose to remove the broken ‘corrode’ 
package.  This is your chance to protest by fixing it!

With the patches below applied corrode still fails to build as it 
does elsewhere: 
<https://github.com/jameysharp/corrode/issues/181>.

The code hasn't seen commits since 2017, nor did I find any newer 
posts by the author on their GitHub issue tracker.  The project is 
quite dead.

Kind regards,

T G-R
