Improve sanitizer configuration and suppress false positives (NVIDIA#5795)

- adds address.sup file to suppress heap-buffer-overflow reports from libapt-pkg
- refactors sanitizer configuration in test_template_impl.sh:
  - moves suppressions configuration to top level
  - adds address sanitizer suppressions file to ASAN_OPTIONS
