Michal Privoznik a156b69c35 tests: Use virTestCompareToString() more
Instead of using:

  if (STRNEQ(a, b)) {
      virTestDifference(stderr, a, b);
      ...
  }

we can use:

  if (virTestCompareToString(a, b) < ) {
      ...
  }

Generated by the following spatch:

  @@
  expression a, b;
  @@

  - if (STRNEQ(a, b)) {
  + if (virTestCompareToString(a, b) < 0) {
      ...
  -   virTestDifference(stderr, a, b);
      ...
      }

and its variations (STRNEQ_NULLABLE() instead of STRNEQ(), then
in some cases variables passed to STRNEQ() are in reversed order
when compared to virTestCompareToString()).

However, coccinelle failed to recognize the pattern in
testNWFilterEBIPTablesAllTeardown() so I had to fix it manually.
Also, I manually fixed testFormat() in tests/sockettest.c as I
didn't bother writing another spatch rule just for that.
