Add a new optional second argument: directory of the xz and xzdec executables. This is need with the CMake build where the binaries end up in the top-level build directory. If ../config.h doesn't exist, assume that all encoders and decoders are available. This will make this script usable from CMake in the most common build configuration. NOTE: Since the existence of ../config.h is checked, the working directory of the test script must be a subdir in the build tree! Otherwise ../config.h would look outside the build tree. Use the default check type instead of forcing CRC32 or CRC64. Now the script doesn't need to check if CRC64 is available.
