[Bug-tar] Race condition in GNU tar test-suite

[Alex Owen]

The Debian Project seems to have found a bug in the tar test suite.
The bug appears to be a race condition in tests/append02.at

I could not find mention of the bug in the bug-tar archives at:
 http://lists.gnu.org/archive/html/bug-tar/
so I'm reporting it now!

This patch makes the race loose consistently and the test will fail
consistently.

I suspect that the Debian Project will just disable the test for the
time being but I guess you GNU tar folks will want to fix the test!
