87a524d931 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().

e21840cfce initd: don't start runsvc for services without exec block 
First in rdsvc, tag the services that *do* have exec lines, even if we don't
read them.

Second, if a service does not have that flag set, don't try to execute it.

056d3c8e64 Add output truncation flag 
This commit adds a "truncate" flag that can be added to a service
description between the "tty" keyword and the path string.

If the flag is set, the output file is truncated to 0 after opening.

This probably requires some remodeling in the future as the tty keyword
no longer deals with just tty devices.
