testsuite/README: update for meson, mention sanitizers

Mention that running outside of `meson test", one needs to set the env.
aka "source scripts/sanitizer-env.sh".

Also gently discourage using sanitizers alongside gdb and strace. While
thing might work it's not the setup we want to support, I think.
