Update Ubuntu essentials list, replace liblz4-tool with lz4

Update the "Ubuntu Essentials package list" by replacing the obsolete
liblz4-tool package name with the current lz4 package name.

According to Quentin Schulz:

"According to pkgs.org, 20.04 lz4 replaces/provides liblz4-tool, same
for 22.04 and 24.04 and for some reason, liblz4-tool requires lz4
package, so I think it should be fine to replace it yes.

"Debian seems to have the same packaging in Bookworm and Bullseye, so
probably fine to do the change. They only seem to be adding a
changelog and copyright, and require lz4 package in any case."

Do we actually need lz4 on the system to run a build? This seems a
little strange to me...

Cheers,

  Good question ... HOSTTOOLS definitely insists that it be there.

I suspect we could/should probably change that (and ASSUME_PROVIDED)
but I your fix is correct as things stand.
