Subject: imgdiff: cache bsdiff suffix array in zip mode.

In zip mode, if a chunk is not deflate or its filename can't be found
in source chunks, the entire source file is used as old data for bsdiff,
To avoid repeatedly construct the suffix array used by bsdiff, we cache
the suffix array of the entire source file.

Bug: 34281147
Test: =time -v imgdiff -z Chrome-ORF74B.apk Chrome-ORF76B.apk Chrome.imgdiff
