ada: Fix late finalization for function call in delta aggregate

The problem occurs at library level because the temporary created for the
function call lives in the elaboration routine but is finalized only when
the package itself is.

It turns out that there is no need for this temporary, since the expansion
of delta aggregates already creates a (properly finalized) temporary.

	* exp_ch6.adb (Expand_Ctrl_Function_Call): Also do nothing for the
	expression of a delta aggregate.
