dtrace: Add WITH_DTRACE_ASAN

Browse source 
This option is a blanket for all the DTrace-related software. The option
when enabled passes in -fsanitize=address -fsanitize=undeifned, enabling
ASAN and UBSAN in the following components:

 - libdtrace
 - dtrace(1)
 - lockstat(1)
 - plockstat(1)

The option defaults to "no" and is intended as a developer aid.
