Remove recently added PL/Perl encoding tests

alvherre · alvherre · commit 65558995a214 · 2012-07-17T13:26:25.000-04:00
These only pass cleanly on UTF8 and SQL_ASCII encodings, besides the
Japanese encoding in which they were originally written, which is clearly
not good enough.  Since the functionality they test has not ever been
tested from PL/Perl, the best answer seems to be to remove the new tests
completely.

Per buildfarm results and ensuing discussion.
