Fix system tests for mac

[awharn]

What It Does

Fixes various system test issues to allow the tests to run better on high performance Mac computers and alternate systems.
This includes:

• Skipping tests that rely on CIM for job cancellation
• Appending missing shebang lines
• Making shell scripts user executable
• Fixing DSN name too long errors
• Adding sleeps to scripts that require more time to pass between commands
• Fixing incorrect logic in shell scripts that used until
• Using commands that are intercompatible with MacOS (due to grep -P not existing on Mac)
• Fixing Logs handler incorrectly using client time when no time is specified
• Fixing an HTTP 1.1 socket reuse error with Node 20 and above
• Fixing the wrong port tests to also handle an ETIMEDOUT error due to firewalls dropping traffic instead of refusing it.
