Enabled -race for go test in Makefile

[tsconn23]

After reviewing the initial issue, it appears that all tests do pass
with the go test -race flag. However this flag is not enabled during
build verification b/c it is not included in the Makefile. I made the
change to include it.

In order to test locally with -race enabled, simply type make test.

Fix #35

Unfortunately it doesn't look like this will be doable until the EdgeX project adopts Go v1.15. There's a long-lived issue on the Golang repo about not being able to use -race in an Alpine-based container.

golang/go#14481

If you scroll to the end, you'll see some comments indicating this should be fixed in 1.15.

Closing PR for now.
