lib: Prevent unaligned memory access and fix endianess in LZMA decode library.

LZMA decode library used to retrieve output size by:
  outSize = *(UInt32 *)(src + LZMA_PROPERTIES_SIZE);

'src' is aligned but LZMA_PROPERTIES_SIZE may refer to an unaligned address like
src+5, and using that as integer pointer may fail on platforms like ARM. Also
this will fail on systems using big-endian (outSize was encoded in
little-endian).

To fix this, reconstruct outSize in little-endian way.
