[Spice-devel] [PATCH spice-common 1/2] meson: Fix dependency of generated files

[Frediano Ziglio]

All generated file depends on generated_messages.h which is
generated too.
So add an explicit dependency from all generated file
(except generated_messages.h generator) to generated_messages.h
generator.
This fixes compiling SPICE server where generated_messages.h
was not generated at all.
