perf callchain: Refactor inline_list to store srcline string directly

Browse Source 
This is a preparation for the creation of real callchain entries for
inlined frames. The rest of the perf code uses the srcline string. As
such, using that also for the srcline API allows us to simplify some of
the upcoming code. Most notably, it will allow us to cache the srcline
for a given inline node and reuse it for different callchain entries.
