Fix for bug #13501 "build problem: too many arguments to function my_bool acl_init".
Fix for bug #13501 "build problem: too many arguments to function my_bool
acl_init".

Updated calls to acl_init()/grant_init() in init_embedded_server() - their
signatures were changed recently, now they don't need argument for passing
pointer to THD object (this code was only compiled if one built embedded
server library with --with-embedded-privilege-control switch).


libmysqld/lib_sql.cc:
  acl_init/grant_init() are now used only at server start up so they always
  allocate temporary THD object and don't need argument for passing pointer
  to it.
