build: Fix release builds with enabled FLB_DEBUG

Enabling FLB_RELEASE should enable compiler optimizations. However, if
FLB_DEBUG was enabled at the same time, no optimization settings were
applied. Now, FLB_RELEASE will always enable optimizations and includes
debug information (CMAKE_BUILD_TYPE is RelWithDebInfo).
