Fix conmon attach socket buffer size
The conmon buffer size is 8192, however the attach socket needs two extra
bytes. The first byte of each message will be the STREAM type. The last
byte is a null byte. So when we want to read 8192 message bytes we need
to read 8193 bytes since the first one is special.
check https://github.com/containers/conmon/blob/1ef246896b4f6566964ed861b98cd32d0e7bf7a2/src/ctr_stdio.c#L101-L107
This problem can be seen in podman-remote run/exec when it prints output
with 8192 or more bytes. The output will miss the 8192 byte.
Fixes #11496
