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.
