fix build test by adding --no-cache

Testcase TestBuildResourceConstraintsAreUsed run build without
--no-cache, so if you run this test twice, it will fail the
second time.
TESTFLAGS='-v -run ^TestBuildResourceConstraintsAreUsed$' ./hack/make.sh binary test-integration-cli
[PASSED]
TESTFLAGS='-v -run ^TestBuildResourceConstraintsAreUsed$' ./hack/make.sh binary test-integration-cli
[FAIL]
Because we'll use cID to inspect field and will get empty cID
if we have cache.
