perf tools: Avoid unnecessary work in directory lookups
This patch improves some (common) inefficiencies in the handling of directory lookups: - not using the d_type information returned by the kernel - constructing (absolute) paths for file operation even though directory-relative operations using the *at functions is possible There are more places to fix but this is a start.
