Fixed PR 10386 by removing the need to convert a pid to a task.
* runtime/itrace.c (usr_itrace_init): Changed prototype to take a
task_struct instead of a pid.
* tapset-itrace.cxx (emit_module_decls): Updated usr_itrace_init() call.
* runtime/autoconf-find-task-pid.c: Removed, since only user_itrace_init()
was using it.
* buildrun.cxx (compile_pass): Removed autoconf-find-task-pid.c test.
