[PATCH 2/3] tests: event: add tests for gpiod_line_get_value_bulk events

[Kent Gibson <warthog618@xxxxxxxxx>]

Add tests to verify the behaviour of gpiod_line_get_value_bulk when
applied to a bulk of event lines.

Signed-off-by: Kent Gibson <warthog618@xxxxxxxxx>

In v1.5 only the value of the first line is returned correctly.
