[PATCH] tools/meson.build: Error on enabling virtiofsd and have_system is false

[Mahmoud Mandour]

Previously, on configuring with --enable-virtiofsd and specifying
a target list that does not contain a full-system emulation target,
a spurious error message is emitted. This patch introduces a
meaningful error message for such case.
