comparators:squashfs: consider new retval for 4.5

Santiago Torres-Ariasrequested to merge
fix_squahsfs_4.5 into master

After version 4.5, squashfs distinguishes between fatal (retval==1) and non-fatal (retval==2) errors. As such, we need to accomodate the comparator to also consider this new retval. Update the behavior on the comparator code to also take retval==2 into account.

See upstream commit for more information https://github.com/plougher/squashfs-tools/commit/06fc061ef426672576075f2989f52acd873c0141
