[PATCH] Avoid ActiveState Perl IO in t800[12]

Use sed instead, it comes with cygwin and there is almost no chance of
someone installing a sed with default CRLF lineendings by accident.

I have been seeing failures in the t800x tests from the beginning on, I
believe. Today they annoyed me enough to get them fixed.
The reason of the failures is the usual one: for reasons unexplainable
activestate perl defaults to CRLF lineendings in all output, which in the
testcase changes the whole file.
