Port tests/rmdir/ignore away from GNU/Linux

[Paul Eggert]

tests/rmdir/ignore fails on Solaris 8, but this is due to a
portability bug in the test.  Here's a patch:

2007-11-16  Paul Eggert  <address@hidden>

        Port tests/rmdir/ignore away from GNU/Linux.
        * tests/rmdir/ignore: Don't assume that rmdir($PWD) will fail
        with errno==ENOTEMPTY when $PWD is not empty; Posix also allows
        rmdir to fail with errno==EBUSY.
