doc: free lib pointer before function return (#4720)

Browse Source 
In function main, the pointer lib allocated at line 7 is passed as an
argument to functions uv_dlopen at line 10, uv_dlerror at lines 11 and
17, and uv_dlsym at line 16, but it is never freed before the function
returns at line 24. This results in a memory leak bug.
