    hurd: fix semantic of file_get_children
    
    When first introduced as fsys_get_children, it made sense to return
    the list of children using paths relative to the root of the
    filesystem that was queried.  Making the get_children method part of
    the fsys protocol was a mistake that has since been corrected in
    9366d6b2.
    
    Instead of returning paths relative to the root of the translator,
    return paths relative to the path of the receiving node.
    
    This fixes a problem with the mtab translator.  Previously, the mtab
    translator invoked on a target that was not the root directory of a
    translator would compute invalid paths, e.g.:
    
    /hurd/mtab: /any/path/servers/socket/26 No such file or directory
    
    * hurd/fs.defs (file_get_children): Update comment.
    * libfshelp/translator-list.c (fshelp_get_active_translators): Add
    argument PREFIX.  Filter entries not beginning with PREFIX if
    non-NULL, and omit PREFIX from the returned paths.
    * libfshelp/fshelp.h (fshelp_get_active_translators): Update comment
    accordingly.  Also clarify that both FILTER and PREFIX can be NULL.
    * libdiskfs/file-get-children.c (diskfs_S_file_get_children): Update
    comment, pass prefix to fshelp_get_active_translators.
    * libnetfs/file-get-children.c (netfs_S_file_get_children): Likewise.
