lib: Allow for the DIM library to be modular
Allow the Dynamic Interrupt Moderation (DIM) library to be built as a module. This is particularly useful in an Android GKI (Google Kernel Image) configuration where everything is built as a module, including Ethernet controller drivers. Having to build DIMLIB into the kernel image with potentially no user is wasteful.
