Reverts #23

See https://issues.redhat.com/browse/RHTAPBUGS-386 for more details. The current Go Toolset image is failing with:

go: no module dependencies to download
STEP 4/7: RUN go build -o ./main
error obtaining VCS status: exit status 128
	Use -buildvcs=false to disable VCS stamping.
subprocess exited with status 1
subprocess exited with status 1
Error: building at STEP "RUN go build -o ./main": exit status 1

reverting to the previous commit solves the issue. So reverting for now

CC @yangcao77 for your awareness. Not sure why the 1.19 image is problematic, suppose it could be a bug in the latest go toolset image.
