Subject: libnetfs: track file name in struct peropen

Track the relative path used to obtain a file handle in the
struct peropen.

* libnetfs/netfs.h (struct peropen): New field path.
* libnetfs/make-peropen.c (netfs_make_peropen): Initialize path.
* libnetfs/release-peropen.c (netfs_release_peropen): Free path.
* libnetfs/fsys-getroot.c (netfs_S_fsys_getroot): Initialize path.
* libnetfs/dir-lookup.c (netfs_S_dir_lookup): Preserve the path.
