[actions] Use remote buildbuddy execution for perf actions (#1417)

Summary: Uses the remote buildbuddy executors to run bazel builds for
perf experiments.

Type of change: /kind test-infra

Test Plan: Tested by pushing a branch and [manually
triggering](https://github.com/pixie-io/pixie/actions/runs/5191523093).
Cancelled it before the last one finished because I tore down the
executors it was running on but it clearly works if the other 5
experiments were passing.
