Handle go test generated executable name in itest/kprobe_test.go (#69)

When newer `go test` runs, it writes the executable to a temporary path (under `/tmp`) under the name `itest.test`. However, if the same test executable is compiled and executed from the project directory the executable name has an underscore.

This PR updates the itest to accept both.
