[PATCH v2 1/2] selftests: helpers: handle multi line in test_sysfs_prop_optional_list

[Boris Shtrasman]

Modify test_sysfs_prop_optional_list to allow multi line parameters, in
order to comply with checkpatch output that limit line by 100 chars.

Allow use cases like:

test_sysfs_prop_optional_list \
        property_name "value1","value2","val3","very_long_option"\
        ,"extra_long_option" \
	,"even_more_data"
