[libcamera-devel] [PATCH] meson.build: Silence the C99 designators warning

[Laurent Pinchart]

We use array designators for array initialization, which is a C99
extension. clang-10 warns about it, causing a build failure.

As this is a useful extension, silence the warning. This needs to be
done only if the compiler supports the -Wno-c99-designator argument,
otherwise a -Wunknown-warning-option will be generated.
