test: dma_perf: make completion event wait period configurable

In certain situations it can be useful to configure the completion event
waiting period instead of using the default hard-coded value, thus it is
now configurable with nanosecond precision with the new `-w` option.

Additionally, current default is changed to one (1) second, as this
should make the tester a bit more responsive in case of a timeout.
