fix: cutpath for ../ paths

[acpana]

Signed-off-by: Alex Pana 8968914+acpana@users.noreply.github.com

I missed specifying the prev dir relatively in my original cut trick: #2443 and this was raised in #2495. Fixes #2495 .

The issue was the cut didn't work w paths prefixed w ../. Added tests for that now.

Also, if you want to see it in action now for these kinds of paths:

# prev dir relative
$ gator verify ../gatekeeper/test/gator/verify/suite.yaml
ok      ../gatekeeper/test/gator/verify/suite.yaml      0.011s
PASS

# prev dir relative specified explicitly
$ gator verify ./../gatekeeper/test/gator/verify/suite.yaml
ok      ./../gatekeeper/test/gator/verify/suite.yaml      0.011s
PASS

# prev dir relative, recurse
$ gator verify ../gatekeeper/test/gator/verify/...
ok      ../gatekeeper/test/gator/verify/more_suites/suite copy.yaml     0.011s
ok      ../gatekeeper/test/gator/verify/more_suites/suite.yaml  0.007s
ok      ../gatekeeper/test/gator/verify/suite.yaml      0.009s
PASS

i'm not too concerned about an infinite loop here since specifying an arbitrarily large number of prev directories has to happen for that
