This does not fix the bug. It only disables the failing test.

If the server failed to expired log files during start up it could crash.

      
the reason for the failure is that io thread passes through a sequence of state
changes before it eventually got stuck at the expect running state as NO.
It's unreasonble to wait for the running status while the whole idea of the test is
to get to the IO thread error.

Fixed with changing the waiting condition.

explicitly with preserving logics of a an old target bug fixes verification.

Pull out some of unpack_dirname() into normalize_dirname(); this
new function does not expand "~" to the home directory.  Use this
function in unpack_dirname(), and use it during init_default_directories()
to remove duplicate entries without losing track of which directory
is a user's home dir.
