[PATCH] Fix potential handle leak by ensuring dlclose is always called on debuginfod_so

function 'dlopen' and lost at debuginfod-client.c:129. In __libdwfl_debuginfod_init, added dlclose(debuginfod_so) after symbol loading, ensuring that the handle is released whether symbols are successfully loaded or not. This prevents potential handle leak reported by static analysis.

[PATCH] debuginfod-client.c: add dlclose call to prevent resource leak
