Garbage collection won’t make a difference here.

According to the definition of the “xfce” and “xfce4-panel” packages,
plugins are searched for on directories listed in the environment
variable “X_XFCE4_LIB_DIRS”.  Try setting that to the directory
containing “xfce4-cpugraph-plugin” before Xfce is started.
