system tests: run test: reenable and fix

Test had incorrectly been disabled for all podman; it
should've been disabled only for podman-remote. Fixed
that, and fixed the problem that was causing failures:
podman-remote is gobbling up stdin (#4095), so no
tests were actually being run at all, or only one.
Fixed by redirecting input on the run_podman invocation.
Added, as backup, a confirmation mechanism to ensure
that all expected tests are being run.

Note that test is reenabled, but the output check is
disabled for podman-remote due to #4096; this at least
lets us check exit status.
