    Keep track of name, not dentry, in vma tracker.
    
    Now even the vdso has a module name.
    
    * runtime/task_finder_vma.c (__stp_tf_vma_entry): Remove dentry, add name.
      (stap_add_vma_map_info): Take and store name argument, not dentry.
      (stap_find_vma_map_info): Likewise.
      (stap_find_vma_map_info_user): Likewise.
    * runtime/sym.c (_stp_umod_lookup): Lookup name directly with
      stap_find_vma_map_info.
    * runtime/vma.c (_stp_vma_match_vdso): Pass "vdso" as name.
      (_stp_vma_mmap_cb): Extract and store name from dentry.
