wpa_supplicant and wpa_cli had already moved to allowing up to 4096 byte buffer size to be used for control interface commands. This was limited by the line edit buffer in interactive mode. Increase that limit to match the other buffers to avoid artificially truncating long commands. Signed-off-by: Jouni Malinen <j@w1.fi>
