Copies of /proc/kallsyms, /proc/modules and an extract of /proc/kcore can
be stored in the perf.data output directory under the subdirectory named
kcore_dir. Guest machines will have their files also under subdirectories
beginning kcore_dir__ followed by the machine pid. Make has_kcore_dir()
return true also if there is a guest machine kcore_dir.
