[mellanox]: Disable caching for the issu-version file (#9235)

The issu-version file for Mellanox is generated from the Mellanox SDK
libraries. The SDK is installed into a Buster docker container, but the
issu-version file goes onto the base OS, which is Bullseye. To work
around this, the issu-version build rules explicitly copies the
issu-version file to target/files/bullseye/ during the Buster build.

Because of our build infra, if caching is enabled and a cache is being
used, then for issu-version, since it is technically built as part of
Buster, then only target/files/buster/issu-version is saved into the
cache, and target/files/bullseye/issu-version isn't cached. If this
cache gets used, then target/files/bullseye/issu-version is missing, and
the final image build fails.

This is to work around the current build issue where Mellanox builds are
failing. This is so that issu-version is always "built", so that copy is
made into the bullseye directory.
