Subject: components/liveinstall: Shrink chunksize to 128KiB and raise to level
 8 LZMA compression

It seems the larger chunk size seems to slow the start of images in
low memory environments due to the ldconfig cache generator unit
eating gigabytes of memory from mapping the chunks into memory.

Attempt to work around this by lowering the chunk size while raising
the compression level to attempt to maintain image sizes.
