tests/cd9660: replace compressed blob with readable hexdump

This test is skipped in most circumstances because it creates a file
whose apparent size is 4.5 GB. It's an ISO 9660 image though,
containing mostly null bytes. Nevertheless, tmpfs doesn't allow such a
big file to be created, so this test is skipped in settings where /tmp
is on a tmpfs.

If the test is run, the ISO image is uncompressed, which takes several
minutes. Replace bzip2 with direct file creation from a hex dump of
that disk image, which is easier to inspect manually and also faster by
about 3 magnitudes.

Add a test case for PR kern/48787.

PR 57803: fix typo in test title.

branches: 1.4.2; 1.4.6;
Update disk-space-available requirement to match reality, and leave a
little extra just in case. The test file is much larger than previously
indicated.

Thanks martin@ for detailed investigation.

Convert size check to use 1K blocks (more human-friendly), and fix
atf_skip message to reference block size rather than bytes.

OK martin@

Set a bigger timeout - this test needs > 3000s on my shark (mostly for
unpacking the test image)
