perf tools: Shorten sample symbol resolving function signature

Since two of the parameters come from the same 'struct
addr_location', rename machine__resolve_bstack() to sample__resolve_bstack()
and pass the that addr_location instead.

This is also for consistency with the same change that resulted in the
sample__resolve_mem() function.
