pass: Migrate gopass script to work for pass

Moved all invocations of gopass to pass. Changed the inner workings of a
few functions to cope with the fewer utility functions in pass instead
of go (no auto-clipping, no flat item listing).

Perhaps still somewhat brittle but should overall have feature parity to
older rofi-gopass script.
