[PINS] update sonic-p4rt docker to bullseye

[rhalstea]

Why I did it

SONiC is migrating to bullseye. This will update the sonic-pins container to bullseye.

How I did it

The sonic-pins code isn't dependent on any architecture so it will already build successfully for bullseye. This PR updates the docker to use bullseye.

How to verify it

Today we cannot build the docker-sonic-p4rt.gz target (e.g. Issue #9885). With this change the docker will build successfully. The P4RT executable will not run, because of a missing runtime library, libgmpxx, which I'll address in a followup PR.

Which release branch to backport (provide reason below if selected)

None.

Description for the changelog

Update docker-sonic-p4rt.gz target to build with Bullseye instead of Buster.

Thanks @rhalstea for working on this!

Here's the fix on the packaging side: sonic-net/sonic-pins#4
After that's merged, we'll need to just update the submodule.

@rhalstea @bocon13 I faced the same build error when I build libsairedis locally, how can I fix this, thanks!:

ERROR: invalid type '' for SAI_ACL_COUNTER_ATTR_TABLE_ID
ERROR: flags are not defined for SAI_ACL_COUNTER_ATTR_TABLE_ID
ERROR: FATAL ERROR === MUST FIX === : Can't use an undefined value as an ARRAY reference at parse.pl line 1676.

@pettershao-ragilenetworks I haven't looked into the siaredis issue. This fix is addressing the incompatibilities in the p4rt docker. Have you tried the suggestions in this comment: #9885 (comment)

Thanks @lguohan, Is there anything else needed before we merge this?
