Assert a command (built with program and args) stderr string is less than or equal to an expression.
Pseudocode:
(program1 + args1 ⇒ command ⇒ stderr) ≤ (expr into string)
§Example
use assertables::*;
let program = "bin/printf-stderr";
let args = ["%s", "alfa"];
let bytes = vec![b'z', b'z'];
assert_program_args_stderr_le_expr!(&program, &args, &bytes);
