zfs receive: add test to reproduce issue #18344

[GarthSnyder]

This is a test that demonstrates issue #18344. I've added redacted streams of both endiannesses and a harness that attempts to zfs recv the opposite-endian version. This should be marked as a known issue if I've set it up correctly.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Performance enhancement (non-breaking change which improves efficiency)
• Code cleanup (non-breaking change which makes code smaller or more readable)
• Quality assurance (non-breaking change which makes the code more robust against bugs)
• Breaking change (fix or feature that would cause existing functionality to change)
• Library ABI change (libzfs, libzfs_core, libnvpair, libuutil and libzfsbootenv)
• Documentation (a change to man pages or other documentation)

Checklist:

• My code follows the OpenZFS code style requirements.
• I have updated the documentation accordingly.
• I have read the contributing document.
• I have added tests to cover my changes.
• I have run the ZFS Test Suite with this change applied.
• All commit messages are properly formatted and contain Signed-off-by.

Pull request overview

Adds a ZFS Test Suite case intended to reproduce OpenZFS issue #18344 (failure to zfs receive a redacted send stream produced on the opposite endianness), by shipping pre-recorded redacted send streams for both byte orders and a harness that selects the opposite-endian stream at runtime.

Changes:

• Add redacted_opposite_endian functional test that attempts to receive a prebuilt opposite-endian redacted stream into POOL2.
• Add big-endian and little-endian redacted send streams (.zsend.bz2) to the test data distribution.
• Register the new test in the runfile and mark it as a known failure linked to issue #18344 in zts-report.py.in.

Should this be a part of #18372 instead of marked as ignored? Or it triggers more than that one issue?
