internal/fastwalk: don't cross Dirent.Reclen boundry while looking for NULL in parseDirEnt

Crossing Dirent.Reclen boundry was manifested in golang/go#28131 as garbaled filenames,
when Dirent.Name was not NULL terminated on FreeBSD due to a bug (parseDirEnt would find a NULL
in the following Dirent's Fileno/Reclen fields).

Only search for NULL on linux, when the Namlen field is available use it directly instead.

Updates golang/go#28131
