[PATCH i-g-t v8 1/3] tests/chamelium/kms_chamelium_edid: Use extended flag to reduce the number of edid

[Pranay Samala]

This test iterates on all the available edids of HDMI.
Due to CI test timeut limitation, we are reducing the
number of edids to execute to avoid result as timeout.

Using extended flag to achieve this. The test will execute
only 25 edids when this flag is not used as CI doesnt uses
this flag.
In local execution to execute on all edids, we have to give
this flag at the runtime.
