Skip plugins list/load/tests for MUSL_OPTIMIZED_BUILD

Browse Source 
When MUSL_OPTIMIZED_BUILD is specified, falco is statically linked under
musl, and can't dlopen() files: see
https://inbox.vuxu.org/musl/20200423162406.GV11469@brightrain.aerifal.cx/T/

So skip listing/loading/testing plugins when MUSL_OPTIMIZED_BUILD is specified.
