selftests: drv-net: Make command requirements explicit

Make require_cmd() calls explicit about whether commands are needed
locally, remotely, or both.
Since require_cmd() defaults to local=True, tests should explicitly set
local=False when commands are only needed remotely.

- socat: Set local=False since it's only needed on remote hosts.
- iperf3: Use single call with both local=True and remote=True since
  it's needed on both hosts.

This avoids unnecessary test failures when commands are missing locally
but available remotely where actually needed, and consolidates a
duplicate require_cmd() call into single call that checks both hosts.
