Should we defer the NULL check to qtest_has_machine_with_env()?
It uses g_str_equal() which is described as:

   Note that this function is primarily meant as a hash table
   comparison function. For a general-purpose, NULL-safe string
   comparison function, see g_strcmp0().

Better switch to g_strcmp0() in qtest_has_machine_with_env()?
