perf machine: Add inline information to frame pointer and LBR callchains

Use append_inlines() in frame pointer and LBR cases.

Update the addr2line test to also test frame pointers.

LBR is also updated but inaccuracy in the branched to IP means the
inline information is missing in the leaf.

Leave LBR callchains untested for now.
