uti: Hook system calls by binary-patching glibc

(1) Add --enable-uti option. The binary-patch library is
    preloaded with this option.
(2) Binary-patching is done by syscall_intercept developed by Intel

This commit includes the following fixes:

(1) Fix do_exit() and terminate() handling
(2) Fix timing of killing mcexec threads when McKernel thread calls terminate()
