remove on HP-UX 11

[Bruno Haible]

The 'remove' test fails on HP-UX 11.11 and 11.31:

  test-remove.c:81: assertion failed
  sh[10]: 26604 Abort(coredump)
  FAIL: test-remove

The reason is that a particular remove() call fails with EEXIST, not with
the expected EINVAL or EBUSY. This patch fixes it. OK to commit?

        remove test: Avoid failure on HP-UX 11.
        * tests/test-remove.c (main): Allow EEXIST as alternative error code.
