uni2ascii @4.18 needs the standard automake1.13 fix

[cooljeanius (Eric Gallager)]

When trying to build uni2ascii, I came across the following familiar error:

--->  Configuring uni2ascii

Pretty standard, so should be pretty easy to fix

Maintainer timeout. Amended the existing configure.ac patch to fix this in r103030. Also made an unrelated change to the Portfile so that users who had already encountered this error will, upon selfupdate, have the work directory automatically cleaned.
