usb: Arm seccomp policy needs _llseek, not lseek
usb: Arm seccomp policy needs _llseek, not lseek

Since our Arm version is a 32-bit process, it uses the _llseek syscall
rather than lseek for 64-bit file offset support.  Fix the seccomp
filter to match.

Fixes a SIGSYS when attaching a USB device to Linux VM on Arm.

BUG=None
TEST=Attach USB device to kevin; verify device in `adb devices`
