[FLINK-37181][build] Fix MacOS sha256sum tool compile error

[gaborgsomogyi]

What is the purpose of the change

The maven command is failing in the following way due to a wrongly working MacOS tool called sha256sum:

Running `/Users/gaborsomogyi/flink/mvnw`...
Error: Failed to validate Maven wrapper SHA-256, your Maven wrapper might be compromised.
Investigate or delete /Users/gaborsomogyi/flink/.mvn/wrapper/maven-wrapper.jar to attempt a clean download.
If you updated your Maven version, you need to update the specified wrapperSha256Sum property.

The issue is that sha256sum is not working as described in the manual:

In all cases, each file listed on the command line is processed separately.  If no files are listed on the command line, or a file name is given as -, input is taken from stdin instead.

Manual test:

$ echo '3d8f20ce6103913be8b52aef6d994e0c54705fb527324ceb9b835b338739c7a8  /Users/gaborsomogyi/flink/.mvn/wrapper/maven-wrapper.jar' | sha256sum -c    
usage: sha256sum [-bctwz] [files ...]
$ echo '3d8f20ce6103913be8b52aef6d994e0c54705fb527324ceb9b835b338739c7a8  /Users/gaborsomogyi/flink/.mvn/wrapper/maven-wrapper.jar' | sha256sum -c -  
/Users/gaborsomogyi/flink/.mvn/wrapper/maven-wrapper.jar: OK

In short sha256sum works only when file name is given as - so in this PR I've added explicit file name.

Brief change log

Added explicit file name to sha256sum and shasum.

Very strange, I'm not sure if this is the reason. When I cloned flink at the beginning of last month, I could still run mvnw under macos. A few weeks later, I ran mvnw again and the same problem occurred as yours

If you think the root cause is something different then please share the details. In my case the mentioned code caused it.
Does this work on your end?

Sorry I can't provide more details, I always get Maven wrapper SHA-256 verification failure now, but your modification did solve this problem under macos

[gaborgsomogyi]

Good to hear it's working on your side too.

[gaborgsomogyi]

Some unrelated tests are flaky so restarting.
