edit: Increase buffer size to 4096 bytes

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.
