Updated get_arch() function in linux/installer/common/psw/createTarball.sh script to support all system languages.

The old get_arch() function would only work on systems configured in English, since it looked for the 'Class:' string.
The new get_arch() function uses the 'magic' information from the readelf output to determine the architecture of the build from generated binary.
