selinux: fix labeling of /proc/net inodes
The proc net rewrite had a side effect on selinux, leading it to mislabel the /proc/net inodes, thereby leading to incorrect denials. Fix security_genfs_sid to ignore extra leading / characters in the path supplied by selinux_proc_get_sid since we now get "//net/..." rather than "/net/...".
