pkg/system: fix missing assertions and use sub-tests for ChTimes
These tests were effectively doing "subtests", using comments to describe each,
however;

- due to the use of `t.Fatal()` would terminate before completing all "subtests"
- The error returned by the function being tested (`Chtimes`), was not checked,
  and the test used "indirect" checks to verify if it worked correctly. Adding
  assertions to check if the function didn't produce an error.
