Ryan Houdek ba93bdd66d FEXRootFSFetcher: Improve hashing performance ...

Don't use pread, instead map the file and madvise larger blocks. This
removes copying overhead as its just mapping file pages in instead.
Also splits the implementation of file reading from hashing to make
tinkering less involved, as if I want more performance out of this (say
due to live hashing) then it's easier to tinker.

Improves hashing performance from ~2.2GB/s to ~3.6GB/s on my system,
which is CPU bounded by xxhash here.
