Fix AdjustUpgrade.pm's view conversion list for --with-lz4.

Fix AdjustUpgrade.pm's view conversion list for --with-lz4.

Turns out the compression.sql test creates a view that needs
to be adjusted in the wake of 47bb9db75 --- except that without
--with-lz4, it fails to create the view at all, so I'd not
noticed this in testing.
