Entry Point function name too long

[zanzaben]

Describe the bug
When trying to run the cfe test runner I got this error

1980-012-14:03:20.46280 ES Startup: Loading file: /cf/cfe_testrunner.so, APP: TESTRUN_APP
OS_GenericSymbolLookup_Impl():118:Error: CFE_TestRunner_AppM: ./cf/cfe_testrunner.so: undefined symbol: CFE_TestRunner_AppM
1980-012-14:03:20.46306 ES Startup: Could not find symbol:CFE_TestRunner_AppM. EC = 0xFFFFFFFF

It should be trying to use CFE_TestRunner_AppMain but is getting truncated at 19 characters.
When I shortened the function name it worked fine.

To Reproduce

1. add the start test scripts for the startup test. Found Here
2. Start it.

Expected behavior
It should run the tests.

System observed on:
Ubuntu 20.04

@jphickey should CFE_TestRunner_AppMain be shortened to something like CFE_TestRunner_AM or should it be able to work with function names longer than 19 characters?

[jphickey]

Since AppMain suffix is used elsewhere (sample apps, LAB apps, etc), how about CFETR_AppMain?

[jphickey]

Another option - drop the CFE, because in reality it can be used for apps too - and call it TestRunner_AppMain

[skliper]

I like CFE_TR_AppMain since it's provided by CFE

I think CFE_TR_AppMain is the most consistent with other function names.
