Subject: [PATCH] Drop support for lz4 < 1.3.0
lz4-r130 was released on May 29th, 2015. Let's drop the work-around for older
versions. In particular, we won't test any new code against those ancient
releases, so we shouldn't pretend they are supported.
(cherry picked from commit e0a1d4b049e6991919a0eacd5d96f7f39dc6ddd1)
Resolves: #1843871
