Subject: Add destructor to libttrace

Add destructor to libttrace

T-trace doesn't considering the case of dlclose().
If some package that use traceBegin, traceEnd call
dlopen(), dlclose() repeatly,
happen fd leakage at ttrace_tmp, trace_marker.
So, Add destructor function libttrace_fini()
that close all of opened file descriptor.
