Changes since 1.6: +1 -8 lines

Remove hack introduced in revision 1.6 to workaround a bug in atf-run that
would cause it to lock up while waiting for the p2k_ffs_fillfs test case
to complete (in some cases only).

This has been fixed by the upstream revision
3dd2481ec97b2fde76521939b6451d03ce989745 which I have just pulled into
our copy of atf.
