pidfs: preserve thread pidfds reopened by file handle
PIDFD_THREAD shares O_EXCL. do_dentry_open() clears O_EXCL after
pidfs_export_open() validates the flags, so open_by_handle_at()
silently turns a thread pidfd into a process pidfd.
Restore PIDFD_THREAD on the opened file, matching pidfs_alloc_file().
