Subject: configure: add --enable-sanitize, use in jenkins.sh

--enable-sanitize adds address sanitizer CFLAGS/CPPFLAGS to the entire build.
Also pass UBSAN_OPTIONS to the test suite run (only has effect during runtime).

Add this flag to jenkins.sh's configure step. To ensure that we get the
sanitize results, add 'make check' to jenkins to catch sanitize failures;

Keep 'make distcheck' without ASAN; it has its own configure which omits
--enable-sanitize. This way we test both with and without ASAN.
