Do not skip 'fs.binfmt_misc.status' by sysctl probe

Directory /proc/sys/fs/binfmt_misc is a separate file system,
mounted by systemd-automout and is represented by an autofs
entry in /etc/mtab. /proc/sys/fs/binfmt_misc is mounted
on demand when accessed. If accessed the first time, we don't
have a way to determine the if the autofs is remote or local.
See 309f823.
However, we don't see a reason why not to traverse the whole
/proc/sys regardless the type of file systems mounted there.
