Hardening system command codemod hardens usage of constant data

[nahsra]

If you have code that looks like either of these:

private static final A = "a";
Runtime.getRuntime().exec(new String[]{"a", "b", "c"});
Runtime.getRuntime().exec(new String[]{A, "b", "c"});

... the codemod will change it, even though it's deducible that it's hardcoded/constant.
