Stop linking sanitized applications with -lutil and -lkvm on NetBSD

The proper approach is to rebuild libutil and libkvm with a desired sanitizer.
An alternative approach to reimplement these functions (and other ones like
curses(3), editline(3) etc) does not scale and enforces linkage every single
binary with these libraries.
