tty: move N_TTY_BUF_SIZE to n_tty



"N_TTY_BUF_SIZE" is private to n_tty and shall not be exposed to the
world. Definitely not in tty.h somewhere in the middle of "struct
tty_struct".

This is a remnant of moving "read_flags" to "struct n_tty_data" in
commit 3fe780b3 ("TTY: move ldisc data from tty_struct: bitmaps").
But some cleanup was needed first (in previous patches).
