Fix #132, Adds CheckStatus helper functions

[chillfig]

Describe the contribution

• Fixes main - cyclomatic complexity of 21 #132, This improvement reduces the cyclomatic complexity of the main() function from 21 to 8 which is less than the recommended 15 cyclomatic complexity upper limit. The change accomplishes this improvement by adding two new status-checking helper functions.

Testing performed
CI

Expected behavior changes

• No impact to behavior. This change distributes complexity to newly created helper functions.

System(s) tested on

• OS: Ubuntu 20.04

Additional context

• Note, that this improvement doesn't reduce the overall complexity of the elf2cfetbl program. It just distributes the complexity across the two new helper functions which each have 1 cyclomatic complexity, potentially making the code easier to understand and maintain.
• Also note that the multiple return() statements are replaced with exit()via the two new helper functions. Calling return() from main() when no other non-daemon threads are running, will have the same effect as calling exit(). It will terminate the process. I chose to use exit() to make use of the new helper functions since elf2cfetbl does not appear to use multi-threading.
