Title:
  Reading /proc/self/task/<pid>/maps is not remapped to the target

Status in QEMU:
  Expired

Bug description:
  Seeing this in qemu-user 3.1.0

  The code in is_proc_myself which supports remapping of /proc/self/maps
  and /proc/<pid>/maps does not support remapping of
  /proc/self/task/<pid>/maps or /proc/<pid>/task/<pid>/maps. Extending
  is_proc_myself to cover these cases causes the maps to be rewritten
  correctly.

  These are useful in multithreaded programs to avoid freezing the
  entire program to capture the maps for a single tid.
