fix(unsquashfs): fix Fatal Error when using unsquashfs
Metadata
Current evaluation
Closed unmerged as overlapping work: PR #5136 (commit 2e7f5c3b) delivered the same squashfs-tools 4.6.1/Core24 update in Snapcraft 8.6.
Resolution: closed superseded
Reason: The author closed #5147 to avoid overlap after #5136 landed. That merged PR delivered the equivalent fix and was scheduled for Snapcraft 8.6.

Issue body
When trying to push a big snap to the snap store, snapcraft fails with the error
FATAL ERROR: Data queue size is too large
This is a bug in unsquashfs tool 4.5. But it has been fixed in 4.6.1, the current stable.
This patch builds squashfs-tools version 4.6.1 from the GIT repository, thus fixing this problem.
