new test, specifically for chmod bug fix

[Jim Meyering]

I've added a new test, specifically for the chmod bug.

2006-09-20  Jim Meyering  <address@hidden>

        * tests/chmod/inaccessible: New test, specifically for this bug.
        Based on a test case from Paul Eggert.
        * tests/chmod/Makefile.am (TESTS): Add inaccessible.
