[PATCH 2/2] tests: Use new grub-fstest option -E with iso9660_ce_loop test

[Thomas Schmitt]

This part of tests/iso9660_test works on an intentionally bad ISO which
with older versions of GRUB will cause an endless cycle. Therefore the
test runs grub-fstest under the program timeout. A non-zero exit value
is taken as indication that the timeout was triggered. Non-empty output
from grub-fstest is taken as indication that a CE entry was skipped by an
old bug, thus breaking the endless cycle by mistake.

A change in grub-fstest causes output of an error message and a non-zero
exit value when the bad ISO is handled properly.

So add the new grub-fstest option -E to the run of grub-fstest on
iso9660_ce_loop.iso and iso9660_ce_loop2.iso. This suppresses the error
message and the non-zero exit value.
