Set the newly-added flags parameter on the OS_ModuleLoad properly to allow an app to be properly unloaded, which in turn allows the reload command to work as expected.

Describe the contribution
Set the flags parameter on the
OS_ModuleLoad()properly to allow an app to be properly unloaded, which in turn allows the reload command to work as expected.Fixes #952
Testing performed
Build and run all unit tests
Test CFE app reload procedure:
OS_printf()call during startup, and install assample_new.so/cf/sample_new.soExpected behavior changes
Module unload/reload works as expected on Linux. Previously the unload would not actually unload, so it would end up restarting the same app code over again.
System(s) tested on
Ubuntu 20.04
Additional context
Needs sync delete fix in OSAL (see nasa/osal#642) to avoid task delete race condition. Without this OSAL change, the task may still be running at the time CFE ES unloads it, which will likely cause a segfault/crash if that happens.
