Remove dependency to Unix from module Profile

Looking at the source code of Sys.time reveals that it is exactly what
is computed by Profile.get_time. This can also be tested by evaluating:

  Sys.time () -. Unix.(let x = times () in x.tms_utime +. x.tms_stime);;

in an OCaml toplevel with Unix.

This allows to put Profile in grammar.cma without the dependency to
unix.cma while preprocessing.
