Reviewed by Tony Chang.

Because not all external storage cards will be formated using a file
system that supports named pipes, Chromium has been changed to creating
the pipes in a temporary folder on the internal storage. Adapt this in
WebKit so we can continue to run layout tests.

This also includes an *unreviewed* fix for a breakage in the webkitpy
tests I made in r129221. Two lines and related to this code, so I decided
to include it in this change.
