aosp/2291528 should have had the `binder_call` macro in hal_can.te be a
`binder_use` macro instead. This fixes that.

Test: AIDL CAN HAL starts up and configures

This macro creates the necessary neverallow to assert the
hal_can_*_{client,server} attribute has exclusive ownership of
the service.

As suggested by nnk@, I have moved the definition for usb_serial_device
to system/sepolicy/public/device.te from
/system/sepolicy/public/hal_can.te.

Test: Manually bring up SLCAN device on test hardware with this change
in place
Change-Id: I0a11556a7eae0be2c9e4b090b051969566c2343e
SLCAN setup requires certain ioctls and read/write operations to
certain tty's. This change allows the HAL to set up SLCAN devices while
complying with SEPolicy.
In addition to adding support for SLCAN, I've also included permissions
for using setsockopt. In order for the CAN HAL receive error frames from
the CAN bus controller, we need to first set the error mask and filter
via setsockopt.
