Increase MAX number of arguments to a service 32 -> 64

Usually a wrapper script is recommended, but for some use-cases it
is more efficient to just be able to use more command line args.

Example application that needs this; udhcpc

Note, we should refactor this to use a dynamically allocated array
instead of this static one.  We relied heavily on static arrays in
Finit 1, when everything had to fit i shm.  This is just legacy.
