external/jpeg-turbo: Fix calling convention confusion in asm code

...which becomes evident with recent Clang trunk versions, and is fixed for
libjpeg-turbo master with <https://github.com/libjpeg-turbo/libjpeg-turbo/
commit/8b2c04f774d18e05e321ee67a9a38b4d7e84f168> "Fix x86-64 ABI conformance
issue in SIMD code" (but unfortunately needs a quite different patch for our
libjpeg-turbo 1.3.1 tarball).
