[dupl] warning: 'SecTrustedApplicationCreateFromPath' is deprecated on macOS 10.15 Catalina

Related: #56, #59, #60

## Problem

Encountering the following errors on macOS 10.15 Catalina with the latest keyring release:

```bash
cgo-gcc-prolog:203:11: warning: 'SecTrustedApplicationCreateFromPath' is deprecated: first deprecated in macOS 10.15 - No longer supported [-Wdeprecated-declarations]
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Security.framework/Headers/SecTrustedApplication.h:59:10: note: 'SecTrustedApplicationCreateFromPath' has been explicitly marked deprecated here
```

This is reported in [keybase/go-keychain #58](https://github.com/keybase/go-keychain/pull/58) and seems to have been fixed in [keybase/go-keychain #60](https://github.com/keybase/go-keychain/pull/60).

## Proposal

Upgrade the corresponding dependency to use a newer version of keybase/go-keychain.
