package/jpeg-turbo: security bump to version 2.0.3

Browse Source 
Fixes the following security vulnerabilities:

- CVE-2019-2201: In generate_jsimd_ycc_rgb_convert_neon of
  jsimd_arm64_neon.S, there is a possible out of bounds write due to a
  missing bounds check.  This could lead to remote code execution in an
  unprivileged process with no additional execution privileges needed.

For more details, see the upstream bugtracker:
https://github.com/libjpeg-turbo/libjpeg-turbo/issues/361

Additionally, it fixes a number of other issues.  From the release notes:

- Fixed a regression in the SIMD feature detection code, introduced by the
  AVX2 SIMD extensions (2.0 beta1[1]), that was known to cause an illegal
  instruction exception, in rare cases, on CPUs that lack support for CPUID
  leaf 07H (or on which the maximum CPUID leaf has been limited by way of a
  BIOS setting.)

- The 4:4:0 (h1v2) fancy (smooth) chroma upsampling algorithm in the
  decompressor now uses a similar bias pattern to that of the 4:2:2 (h2v1)
  fancy chroma upsampling algorithm, rounding up or down the upsampled
  result for alternate pixels rather than always rounding down.  This
  ensures that, regardless of whether a 4:2:2 JPEG image is rotated or
  transposed prior to decompression (in the frequency domain) or after
  decompression (in the spatial domain), the final image will be similar.

- Fixed a regression introduced by 2.0 beta1[15] whereby attempting to
  generate a progressive JPEG image on an SSE2-capable CPU using a scan
  script containing one or more scans with lengths divisible by 16 would
  result in an error ("Missing Huffman code table entry") and an invalid
  JPEG image.

- Fixed an issue whereby tjDecodeYUV() and tjDecodeYUVPlanes() would throw
  an error ("Invalid progressive parameters") or a warning ("Inconsistent
  progression sequence") if passed a TurboJPEG instance that was previously
  used to decompress a progressive JPEG image.
