revert previous, shell has been fixed.

New sh(1) now complains about unreadable working directories, so make
the tests ignore stderr.

pax(1): Only require getcwd if we're reading without --insecure.

No other paths use the result of getcwd.

PR bin/44498: tar(1) unnecessarily demands that getcwd() work

tests/bin/pax: Add some more cwd-related test cases.

PR bin/44498: tar(1) unnecessarily demands that getcwd() work

tests/bin/pax: Test pax(1) succeeds with empty file list on stdin.

PR bin/41736: pax reports an error when copying zero files

pax(1): Don't require open(".") or getcwd to work for list operation.

PR 44498: tar(1) unnecessarily demands that getcwd() work

tests/bin/pax: Add test for pax list in an ungettable cwd.

The list operation has no need to touch the file system, so it should
have no need for open(".") or getcwd() to succeed.

PR bin/44498: tar(1) unnecessarily demands that getcwd() work

(The PR was filed about tar(1), which is now bsdtar by default, but
the issue applies to pax(1) too and would continue to apply to tar(1)
if you set MKBSDTAR=no.)
