Fix off-by-one error in superblock mode (#3221)

Browse Source 
Fixes #3212.

Long literal and match lengths had an off-by-one error in ZSTD_getSequenceLength.
Fix the off-by-one error, and add a golden compression test that catches the bug.
Also run all the golden tests in the cli-tests framework.
