[PATCH] meson: build chardev trace files when have_block

["Daniel P. Berrangé" <berrange@redhat.com>]

The QSD depends on chardev code, and is built when have_tools is
true. This means conditionalizing chardev trace on have_system
is wrong, we need have_block which is set have_system || have_tools.

This latent bug was historically harmless because only the spice
chardev included tracing, which wasn't built in a !have_system
scenario.
