meson: avoid bogus meson warning

With meson-0.52.0-1.module_f31+6771+f5d842eb.noarch I get:
src/test/meson.build:19: WARNING: Overriding previous value of environment variable 'PATH' with a new one

When we're using *prepend*, the whole point is to modify an existing variable,
so meson shouldn't warn. But let's set avoid the warning and shorten things by
setting the final value immediately.
