fu_util/fobj: fix autorelease pool cleanup in glibc

Browse Source 
glibc's pthread_exit runs stack unwinding for C++ destructor's handling,
and calls destructors for pthread specifics only after unwinding.

This way fobj_destroy_thread_AR is called too lately.

We have to compile with '-fexception' to register all our
attribute((cleanup)) for autorelease pools as "C++ desctructors".

Found in debug session with Sergey Fucanchik <s.fukanchik@postgrespro.ru>
