tty: provide tty_name() even without CONFIG_TTY
The audit subsystem just started printing the name of the tty,
but that causes a build failure when CONFIG_TTY is disabled:
kernel/built-in.o: In function `audit_log_task_info':
memremap.c:(.text+0x5e34c): undefined reference to `tty_name'
kernel/built-in.o: In function `audit_set_loginuid':
memremap.c:(.text+0x63b34): undefined reference to `tty_name'
This adds tty_name() to the list of functions that are provided
as trivial stubs in that configuration.
