rust: disable lz4 block checksum

### Description

Disables the lz4 block checksum to mimic the behaviour of the Go code.

MCAP files from Rust created with a block checksum will currently fail
when run through the MCAP CLI due to
pierrec/lz4#223, so this will ensure greater
compatibility with older MCAP CLI versions.

<!-- Describe the problem, what has changed, and motivation behind those
