pactest: add environment option to run tests with valgrind

In autotools, if we wanted to run tests with valgrind, we used some Make
magic which passed arguments to pactest.py, but that doesn't work in
meson, because all arguments are encoded at configure time. Instead,
let's short-circuit the build runner logic entirely, and teach pactest
to default to running valgrind, when it detects an environment variable
set independent of the build system.

To run the tests with valgrind, we can now use:

PACTEST_VALGRIND=1 meson test -C builddir/

or

PACTEST_VALGRIND=1 make check

It is also possible, but confusing/inconsistent, to use

make check PY_LOG_FLAGS=--valgrind

We *could* add a meson option -Dvalgrind=true, but that is annoying to
reconfigure between test runs, and overall the consensus is it seems
simpler to opt in each time we want to run valgrind, as was already the
case.
