Previously, process_fd did not handle fhandler using archetype correctly. Due to lack of PC_OPEN flag for path_conv, build_fh_pc() could not initialize archetype. Because of this bug, accessing pty or console via process_fd fails.
With this patch, use build_fh_name() with PC_OPEN flag instead of build_fh_pc() to set PC_OPEN flag to path_conv.
