test: Add tests for passt in vhost-user mode
Run functional and performance tests for vhost-user mode as well. For functional tests, we add passt_vu and passt_vu_in_ns as symbolic links to their non-vhost-user counterparts, as no differences are intended but we want to distinguish them in test logs. For performance tests, instead, we add separate perf/passt_vu_tcp and perf/passt_vu_udp files, as we need longer test duration, as well as higher UDP sending bandwidths and larger TCP windows, to actually get the highest throughput vhost-user mode offers. For valgrind tests, vhost-user mode needs two extra system calls: statx and readlink. Add them as EXTRA_SYSCALLS for the valgrind target.
