Fix PR 39650. I now realize I had broken this myself back in March 2007
when I updated to 2.5.5.

Use the correct papersize names. And bump PKGREVISION.

It now just passes along the name set in pkgsrc PAPERSIZE.
It has no checking so could still have wrong value.
I didn't check for "Letterdj" so that may cause problem as mpage
doesn't know it. For the record this is what mpage knows:

Mpage knows about the following paper types:
Type           Points Wide Points High
-------------- ----------- -----------
Letter                 612         792
LetterSmall            612         792
