test_infra: Move remote_command to test_infra

Move remote_command() and remote_command_w_output() from
tests/common/utils.rs into test_infra/src/lib.rs to allow
reuse across crates.

The cloud-hypervisor integration tests already use
'use test_infra::*', so the functions are available
without any caller changes.
