Go: Fix Makefile Path for Unit Test

[edlng]

Running unit-test locally would return Makefile Error 141 (which I think stems from the command treating utils as a different package. This patch makes it work on both CI and local testing.

~ make unit-test
mkdir -p reports
set -o pipefail; \
        go test -v ./... -skip 'Example|TestGlideTestSuite'  \
        | tee >(go tool test2json -t -p github.com/valkey-io/valkey-glide/go/v2 utils | go-test-report -o reports/unit-tests.html -t unit-test > /dev/null)
make: *** [unit-test] Error 141
