security/trezord: Update to unreleased 2.0.34

[des]

Summary

Update to tip-of-tree from GitHub repository. This changes the version
number to 2.0.34 (which has not yet been released) and allows building
the port with newer Go versions.

Note that this software is no longer maintained and it is doubtful that
a new release will ever get tagged.
