ada: Rely on default parameter when making component definition nodes

When calling Make_Component_Definition we can rely on the default value of
parameter Aliased_Present being False. This makes code cleaner and consistent
with relying on the default value of other parameters of this routine, e.g.
Null_Exclusion_Present.

Code cleanup; semantics is unaffected.

gcc/ada/ChangeLog:

	* exp_ch3.adb, exp_ch9.adb, exp_dist.adb, exp_imgv.adb, exp_util.adb,
	sem_dist.adb: Remove explicit actual parameter Aliased_Present equal
	False; tune comments and whitespace.
