ada: Clean up unnecessary nesting in code for DLL libraries

Code cleanup; issue spotted while examining routines with No_ prefix.

gcc/ada/

	* mdll.ads (Build_Import_Library): Fix grammar in comment.
	* mdll.adb (Build_Import_Library): Directly execute code of a
	nested routine; rename No_Lib_Prefix to Strip_Lib_Prefix.
