dashboard/config: drop security modules bits from usb instance
CONFIG_SECURITY_TOMOYO produces a large amount of coverage entries for each
ioctl call. For normal instances, this might not be a problem, as they
call only a single ioctl for each syzkaller syscall.
However, the syz_usb_connect pseudo-syscall calls a large number of ioctls.
As a result, the KCOV coverage buffer for this syscall might overflow due
to the tomoyo-produced entries.
For example, with tomoyo, the first syscall of the vusb_ath9k runtest
produces ~140k KCOV entries (with [1] applied), which is not far from the
current 256k limit of KCOV entries per syscall.
With tomoyo disabled, the number of entries falls to ~30k.
Drop the security modules–related bits from the USB instance: I don't think
they are useful for that instance anyway.
