[Ada] Minor tweak to -gnatR output

[Pierre-Marie de Rodat]

This makes sure that the numbers present in the -gnatR output are
printed in decimal format in all cases, since the hexadecimal format is
not compatible with the JSON syntax.

Tested on x86_64-pc-linux-gnu, committed on trunk

	* repinfo.adb (List_Component_Layout): Pass Decimal to UI_Write.
