Update qemu bazelrc (#1342)

Summary: There were multiple flags for build/test tag filters under the
qemu config. These were a little confusing and conflicted each other.
This collapses the config to one set of flags and alson includes
`requires_root` with the bpf config.

Relevant Issues: N/A

Type of change: /kind cleanup

Test Plan: Ensure the that requires_root tests run on this PR and pass.
