configure: Allow systemtap/DTrace userspace probes to be disabled.
'./configure --disable-probes' will disable these probes. Otherwise
they are autodetected as before.
The <sys/sdt.h> produces lots of errors when you try to compile with
these probes enabled under clang, so it is necessary to provide a way
to disable them for clang users.
