updated dependencies and RPM SPEC

[daniejstriata]

I updated the go.mod. There were 2 protobuf includes:

• github.com/gogo/protobuf v1.3.2 // indirect
• github.com/golang/protobuf v1.3.1 // indirect

which I replaced with:

• github.com/golang/protobuf v1.5.4 // indirect

I also updated opencensus.io from:

• go.opencensus.io v0.22.5 // indirect

to:

• go.opencensus.io v0.24.0 // indirect

I updated the RPM SPEC file.

I compiled this in my branch and did not see any obvious issues.

It's unfortunately not possible to remove/replace gogo/protobuf. It's a dependency for badger: https://github.com/dgraph-io/badger/blob/main/go.mod#L9
