Attachment: Bug 1654259 - Harmonize reftest lines for private fields r?anba

Use the same shell-option + skip-if combo throughout private fields testing.
This skips testing of these in the browser (following the pattern established
for the test262 tests) however we have other pref-driven browser based tests,
which use an eval pattern to avoid failing if the pref isn't set.
