Devel-PPPort - silence maybe-uninitialized warnings on gcc-12

GCC-12 seems to have a propensity to warning about maybe-uninitialized
variables a lot more than it should. Most of the cases I have looked
into it turns out to be a false positive, but at the same time, it is
pretty simple to fix this kind of thing, so just fix it so the darn
thing will shut up.

This one just initializes some variables to NULL at the start of a test
function.

Fixes the following (slightly elided) warning.

    gcc-12 -c ... -Og -g ... -W -Wall RealPPPort.c
    In file included from ../../perl.h:6197,
                     from RealPPPort.xs:31:
