Fix regressions/rhbz557655.sh when debugging is enabled.

The regression test for RHBZ#557655 would fail if debugging was
enabled, because debug output would get mixed up with the test
output.

To reproduce the error do:

LIBGUESTFS_DEBUG=1 make -C regressions TESTS=rhbz557655.sh check

This commit disables debug for just this test.
