### Rationale for this change
<!--
Why are you proposing this change? If this is already explained clearly in
the issue then this section is not needed.
Explaining clearly why changes are proposed helps reviewers understand your
changes and offer better suggestions for fixes.
-->
[IPC files should contain a valid IPC stream with
EOS](https://arrow.apache.org/docs/format/Columnar.html#ipc-file-format). Some
arrow producers don't guarantee that the EOS is written. However there might be
readers depending on simply reading the embedded IPC stream (and depending on
the EOS to avoid reading the Footer as a corrupted message) so we should
validate stream reading from IPC files as well as file reading.
### What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
arrow-json-integration-test will now also try to read a file as a stream,
which will fail if the file doesn't include an EOS or otherwise isn't a valid
stream.
### Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?
-->
yes
### Are there any user-facing changes?
no
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.
-->
<!--
If there are any breaking changes to public APIs, please uncomment the line
below and explain which changes are breaking.
-->
<!-- **This PR includes breaking changes to public APIs.** -->
<!--
Please uncomment the line below (and provide explanation) if the changes fix
either (a) a security vulnerability, (b) a bug that caused incorrect or invalid
data to be produced, or (c) a bug that causes a crash (even when the API
contract is upheld). We use this to highlight fixes to issues that may affect
users without their knowledge. For this reason, fixing bugs that cause errors
don't count, since those are usually obvious.
