package/vorbis-tools: add upstream security fixes for CVE-2014-96{38, 39, 40} 

Fixes the following security vulnerabilities:

- CVE-2014-9638: oggenc in vorbis-tools 1.4.0 allows remote attackers to
  cause a denial of service (divide-by-zero error and crash) via a WAV file
  with the number of channels set to zero.

- CVE-2014-9639: Integer overflow in oggenc in vorbis-tools 1.4.0 allows
  remote attackers to cause a denial of service (crash) via a crafted number
  of channels in a WAV file, which triggers an out-of-bounds memory access.

- CVE-2014-9640: oggenc/oggenc.c in vorbis-tools 1.4.0 allows remote
  attackers to cause a denial of service (out-of-bounds read) via a crafted
  raw file.
