ectool: add servo v2 spi support
Add a new transport for ectool to send host command V3 over the Servo v2
SPI interface using libftdi.
Build this new communication mechanism only for the 'build' architecture
as it has a dependency on libftdi, the new ectool binary is called
ectool_servo.
Fix the 'build' tools build if they don't have a source file matching
their binary name.
The serial number of the servo board can be passed in the 'name'
parameter, e.g. :
sudo ectool_servo --name=905537-00474 version

BRANCH=none
BUG=b:70320279
TEST=with ZerbleBarn connected to a servo V2, run:
sudo ectool_servo version
