meson.build: no -Wimplicit-fallthrough when building with clang

Browse source 
clang does not recognize the fallthrough annotation used in uthash.h, so we
change -Wimplicit-fallthrough to the single argument form currently only
supported by GCC.

We are still detecting implicit fallthroughs with GCC in CI.
