Disable ASAN on linux_bionic timeout_dumper

Run-test does not setup the library path correctly to handle ASAN with
this binary at this time. Just disable it for now.

Test: timeout -k 120s -s SIGRTMIN+2 2s \
         $OUT_DIR/soong/host/linux_bionic-x86/bin/timeout_dumper \
         sh -c 'echo $$; sleep 1000'
