[sr-dev] [kamailio/kamailio] add ASAN build options (#2650)

### Description

I want to be sure my customization does not produce memory leack. To get this work I want to use the ASAN project.

Could you add `mode=asan` build option that adds gcc ` -fsanitize=address -static-libasan` options `-lasan` linker flags.

Maybe important. ASAN expects linked first ``` [root@b276215a3a22 kamailio]# kamailio -DD -E ==13760==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD. ```
