Spack go version is old and messes up building gojsonnet for wire-cell-python

[brettviren]

This is a convoluted problem which did not happen on Debian 11 but occurs when setting things up again with Debian 12.

Spack with wire-cell-spack builds go 1.4 which gets used by pip install the wire-cell-python package in the resulting virtual env. Go is needed directly through gojsonet Python bindings and via moo.

The pip install fails due to error:

      running build_ext
      flag provided but not defined: -buildmode

To fix one can remove from the Spack view the very old go provided by Spack in order to pick up the newer version from the host OS:

rm local/bin/go local/bin/gofmt

A better solution is some mix of:

• upgrade the go package in Spack and/or in wire-cell-spack
• incorporate installing of wire-cell-python dependencies in wire-cell-spack
