DS: Fix some quirks in the NDS build system, remove some dead code

* remove (S)RAM save code (it has not been in use for quite some time)
* remove the lz compressor (was only used by ram save code)
* OPT_SPEED was set incorrectly
* dsmain.cpp was misspelled as ds_main.cpp
* remove unsed arm9 libcartreset (the copy in the arm7 directory
  still is around, though)
