[PATCH] plperl: use xsubpp -output unconditionally

Hi hackers,

I noticed that the PL/Perl makefile makes the use of the -output option
conditional on coverage+vpath, because that option is not supported
until Perl 5.9.3.  But these days we require Perl 5.14, so we can remove
that conditional (which also matches what Meson does).  Please see the
attached.

Subject: [PATCH] Make use of xsubpp -output unconditional

It was kept conditional on coverage+vpath because Perl before 5.9.3
didn't support it, but we now require 5.14, so that's unnecessary.

This also matches what Meson does.
