Changed noop section regex to end of bugreport

In one of the recent devices, surfaceflinger dumpsys contains lines
that match the no_op regex and hence the remaining dumpsys items are
not processed. Hence batterystats parser is returning null.

Affecting string: "------ DrmDisplayCompositor Layer: plane=21 disabled"
