include guards of ls-mat4.h and ov-type-conv.h

[NODA, Kai]

Greetings,

Here is a patch which fixes malfunctioning and lack of include guards.
I noticed these while testing my Bash script which feeds
#include <foo.h>
#include <foo.h>
to cpp and does wc -l on the output.
If the number of lines is twice as large as the case of single #include <foo.h>,
there should be a bug around include guard of foo.h.
