external/cddl/osnet: Supress -Werror=maybe-uninitialized error in libdtrace. 

It looks like this is a false positive, since the section of code triggering the error

external/cddl/osnet/dist/lib/libdtrace/common/dt_proc.c:400:42:

is only accessed after "err" is initialized.

Error was reported when build.sh was run with MKLIBCSANITIZER=yes flag.
