term_nr_ue_signal() frees all memory, except for dfts lib load

Frees all allocated memory, except for library loading related, and ul
reference signal sequences, which are allocated in static variables

- introduce loader_reset() that frees all memory
- resolve memory leak in loader_format_shlibpath()
- correctly handle library reload: check if a function has been
  retrieved already. Don't leak memory (strdup()), and handle multiple
  reloads of different functions from the same SO

- 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.
