If you use the lclstrconst.xx.po (where xx is your language) (together with the translations unit) then all this should be localized.
About the original question.
If these strings aren't localized then feel free to supply a patch.
Add the resourcestring to lclstrconsts unit.
Rebuild the .po files.
(There's a tool in ($Lazarus)/tools)
Edit the pofile of your language to get the proper translation of the new resourcestring.
