iio: tools: make generic_buffer look for "-trigger"

All the ST Sensors use the old "<foo>-trigger" rather than the standard "<foo>-devN" new standard suffix for triggers. Now much to do about it since it is ABI, but make the testing tools recognize it too. Signed-off-by: Linus Walleij <[email protected]> Signed-off-by: Jonathan Cameron <[email protected]>
