test-strip: make test compatible with chg

The test was using reposetup which had the logic for stripping
commits. This leads to a situation where if the reposetup was called twice for
an extension (which can happen with chg running), the stripped node would not
be found the second time. Therefore, this commit changes the test to put the
stripping logic inside commands instead of the reposetup. This ensures that the
stripping logic is invoked only when the command is invoked and thus, avoids
any problems.

Test Plan:
Ran the test 'test-strip.t' with and without the '--chg' option.
