Modified Files:
        src/usr.bin/sockstat: Makefile sockstat.c

Log Message:
RR/54971: scole_mail: sockstat command output incorrect for normal
user As the PR hints, it is not enough to have kern.expose_address=1
to see kernel addresses, we also need to have the PK_KMEM bit set
which we achieve by installing sockstat setgid kmem and opening
and closing /dev/mem. (/usr/src/sys/kern/kern_proc.c:311). It is
unfortunate that we need to give the program more privilege, to
prove to the kernel that we have the privilege to see the data.
