1e60713a68 contrib: Fix test-security-check fail in Ubuntu 18.04 (Chun Kuan Lee)

Pull request description:

  - Fix test-security-check fail in Ubuntu 18.04. Those flags are enabled by default, so we must specify `-no` to make the executable does 'not' have those attributes.
  - Drop HIGH_ENTROPY_VA. After update our gitian system to Bionic, the compiler should support HIGH_ENTROPY_VA
