ANDROID: fs: Restore vfs_path_lookup() export

Browse Source 
Partial revert of 197df04c74 ("rename user_path_umountat() to
user_path_mountpoint_at()"), to restore access to vfs_path_lookup()
without including fs/internal.h, as needed by sdcardfs.

Test: HiKey/X15 + Pie + android-mainline,
      and HiKey + AOSP Maser + android-mainline,
      directories under /sdcard created,
      output of mount is right,
      CTS test collecting device infor works
