cleanup: delete remains of libutil

 - exec_t belongs to service.h, the main place where it is used/needed
 - code for executing exec_t is moved to runsvc for the same reason
 - what is left are NORETURN and ARRAY_SIZE
   - the former can be replaced with direct attribute usage since
     the only relevant compilers all support the attribute.
   - the later is only used in 3 places and can be trivially replaced
     with direct usage of sizeof().
