If processing of a SUSP CE entry leads to a continuation area which
begins by entry CE or ST, then these entries were skipped without
interpretation. In case of CE this would lead to premature end of
processing the SUSP entries of the file. In case of ST this could
cause following non-SUSP bytes to be interpreted as SUSP entries.

The test for the ability to decompress zisofs encoded files is supposed
to fail due to the lack of this ability in GRUB. But it fails early with
xorriso : FAILURE : -volid: Text too long (1650 > 32)
because "ziso9660" is not in the list of filesystems which accept at most
32 bytes in their FSLABEL. If this is fixed, the test returns false
success because the xorriso run does not produce any zisofs compressed
files. The problem is in the sequence of native xorriso commands used.
The command -set_filter_r applies only to the files which are already
inserted into the emerging ISO filesystem. In the current sequence no
files have been inserted yet by command -add when the last of two
-set_filter_r commands is executed. After this is corrected, xorriso
refuses to work because the global settings of command -zisofs can be
made only before command -set_filter_r has attached zisofs filters to
the data files in the emerging ISO. Further: A bug in xorriso causes
a false warning about FSLABEL being too long for Joliet. Shortcomings
of Joliet cause warnings about symbolic links. Such warnings might
distract from the actual reason why the test is expected to fail.
So, add "ziso9660" to the 32-byte FSLABEL list.
Fix the xorriso run to produce compressed files which for now cause
righteous failure of the test. Do this by removing a surplus group of
-set_filter_r and -zisofs commands, by moving the other such group
behind -add, and by swapping -set_filter_r and -zisofs.
Remove the -as mkisofs options which produce a Joliet filesystem tree.

The iso9660_test fails if the effective locale is not UTF-8. This happens
because xorriso needs to convert file names and FSLABEL to UCS-2 when
preparing a Joliet tree. The grub-fs-tester obviously intends to use UTF-8
as character set, but xorriso assumes by default the result of nl_langinfo(3)
with item CODESET. So, override the result of nl_langinfo(CODESET) by options
of xorriso -as mkisofs.
