_FORTIFY_SOURCE requires compiling with optimization (-O)

On a Fedora36 system, attempting to run the make command throws a large number of warnings such as the following:
```
[ 80%] Building CXX object CMakeFiles/camhal_static.dir/modules/ia_cipr/src/Command.cpp.o

```

This patch makes the failures go away, but I don't understand whether there will be performance impact as a result of the change:
