plugins: fix dissector registration with CMake

Noticed when comparing output of `tshark -G fields` between autofoo and
cmake builds. With this change, I see no differences anymore.

While only WiMax needs this change, do a similar thing for consistency
with autofoo and between dissectors (actually, the contents of
${PLUGIN_FILES} minus plugin.c was used).
