qtkeychain-qt5 @0.13.2_0: error: use of undeclared identifier 'errSecOpWr'

[chrstphrchvz (Christopher Chavez)]

errSecOpWr is only defined since the macOS 10.12.4 SDK.

        case errSecOpWr:
             ^~~~~~~~~~
             errSecIO

The following patch might work, but may not be worth bothering with if there many more incompatibilities with macOS < 10.12. I personally do not use macOS versions that old.
