tty: switch count in tty_ldisc_receive_buf() to size_t
It comes from both paste_selection() and tty_port_default_receive_buf()
as unsigned (int and size_t respectively). Switch to size_t to converge
to that eventually.
Return the count as size_t too (the two callers above expect that).
Switch paste_selection()'s type of 'count' too, so that the returned and
passed type match.
