SB unreachable code in CFE_SB_AppInit

[jphickey]

Describe the bug
The following conditional is never reachable with the default config:

cFE/modules/sb/fsw/src/cfe_sb_task.c

Lines 192 to 195 in 2afdbc1

	if (CFE_PLATFORM_EVS_MAX_EVENT_FILTERS < CfgFileEventsToFilter)
	{
	CfgFileEventsToFilter = CFE_PLATFORM_EVS_MAX_EVENT_FILTERS;
	} /* end if */

To reach this would require that the code is built with a config where CFE_PLATFORM_EVS_MAX_EVENT_FILTERS (from platform config, defaults to 8) is less than CFE_SB_MAX_CFG_FILE_EVENTS_TO_FILTER (hardcoded to 8).

To Reproduce
Build code with default config and run coverage report.

Expected behavior
Code could be cleaned up to not have unreachable lines in any config, or at least convert the check such that it can be evaluated at compile time (if CFE_PLATFORM_EVS_MAX_EVENT_FILTERS >= CFE_SB_MAX_CFG_FILE_EVENTS_TO_FILTER then the code becomes unreachable).

System observed on:
Ubuntu

Additional context
Somewhat related to #1468, if this is fixed hopefully it would get both of these
