tests: use unbundle in test-symlink-os-yes-fs-no.py

The test (which should probably be rewritten as a .t test - the
test was initially authored in 2009 and this may have predated
some test harness features allowing us to implement it as a .t
test) is verifying symlink behavior with regards to working
directory operations. How it pulls bundle data into a repo is
not relevant. So we can switch from pull to unbundle so we can
support environments where bundlerepos don't work.
