adi/ad908[1|4]_mc.py: Fix label parsing in _map_to_dict()

[mhennerich]

Description

In recent kernels the IIO core adds labels for all channels with extended names. This now causes undesired behavior. Before splitting, check if the split string is part of the string. This will also catch the 'buffer_only' case.
