ladspa-sink: fix search path

Browse source 
Having a single level macro for stringizing LADSPA_PATH doesn't work,
because the '#' preprocessor operator doesn't expand any macros in its
parameter. As a result, we used the string "LADSPA_PATH" as the search
path, and obviously no plugins were ever found.

This adds a two-level macro in macro.h and uses that to expand and
stringize LADSPA_PATH.
