Play remote system tests do not test proper failure in unsupported cases

[ygalblum]

/kind bug

Description
Some features, e.g. podman play --build, are only supported locally and therefore block the user from using them with podman-remote. However, the system tests skip the relevant tests instead of verifying that the requests properly fail (see https://github.com/containers/podman/blob/main/test/system/700-play.bats#L243)

Steps to reproduce the issue:
Run the system test: PODMAN=./bin/podman-remote bats test/system/700-play.bats

Describe the results you received:
The test "podman play --build --context-dir" is skipped

Describe the results you expected:
The test verifies that the request was properly blockes

@ygalblum @vrothberg Is the goal here to fix the tests or implement podman kube play --build for the remote API?

[vrothberg]

I don't think that supporting --build on remote clients is worth the effort. At least for now where nobody has asked to support it.

So making sure the tests do proper error checks for remote clients SGTM

Still a TODO

There is some demand to add remote build support #24435
so this here can be closed I would say
