uml: boot broken due to buffer overrun
commit 361371201b60ffd686a694c848c1d5ad6061725f upstream.
mconsole_init() passed 256 bytes as length in os_create_unix_socket, while
the sizeof UNIX_PATH_MAX is 108. This patch fixes that problem and avoids
a big overrun bug reported on UML bootup.
sockaddr_un.sun_path is UNIX_PATH_MAX long which causes the problem.
