Enable Address Sanitizer on physical simulators

- install libasan in physim containers
- run physim containers with SYS_CAP_PTRACE capability
- remove static-libasan: not available in RHEL8:

  The physims are tested in a container environment on top of RHEL8. To
  my knowledge, no package provides the static ASan library there.
  Therefore, remove it here to be able to run these tests.
