9p: Add mksock support

Without this patch, an attempt to mksock will get an EINVAL.

Before this patch:
[root@localhost 1dir]# mksock mysock
mksock: error making mysock: Invalid argument

With this patch:
[root@localhost 1dir]# mksock mysock
[root@localhost 1dir]# ls    -l mysock
s--------- 1 root root 0 2010-03-31 17:44 mysock
