libdiskfs: track file name in struct peropen
Track the relative path used to obtain a file handle in the
struct peropen.
* libdiskfs/diskfs.h (struct peropen): New field path.
* libdiskfs/peropen-make.c (diskfs_make_peropen): Initialize path.
* libdiskfs/peropen-rele.c (diskfs_release_peropen): Free path.
* libdiskfs/fsys-getroot.c (diskfs_S_fsys_getroot): Initialize path.
* libdiskfs/dir-lookup.c (diskfs_S_dir_lookup): Preserve the path.
