CMakeLists: use FLB_DEFINTION for FLB_HAVE_*(#6519)

[nokute78]

Fixes #6519
This patch is to fix to use FLB_DEFINITION to define FLB_HAVE_*.

FLB_HAVE_CHUNK_TRACE should be defined in flb_info.h.
However it isn't defined since it is defined using add_definitions.

It causes struct size mismatch between fluent-bit and fluent-bit-plugin since the size will be changed FLB_HAVE_CHUNK_TRACE is defined or not.
