Log:
  libdtrace: Fix another uninitialized dtt_flags UB
  
  Like r331073, eliminate a UB by fully initializing the struct with a designated
  initializer.  Note that the similar src_dtt is not fully used, so a similar
  treatment was not absolutely required.  I chose to leave it alone.  It
  wouldn't hurt to do the same thing, though.
