Update libarchive to 3.0.3

Some of new features:
  - New readers: RAR, LHA/LZH, CAB reader, 7-Zip
  - New writers: ISO9660, XAR
  - Improvements to many formats, especially including ISO9660 and Zip
  - Stackable write filters to write, e.g., tar.gz.uu in a single pass
  - Exploit seekable input; new "seekable" Zip reader can exploit the Zip
    Central Directory when it's available; the old "streamable" Zip reader
    is still fully supported for cases where seeking is not possible.
