[0/2] minimal run-time audit support

  This patch-set introduces the bare minimum functionality for working
with audit modules at run-time.

Patch1 fixes the check in dlmopen() which avoids loading solibs into
the auditing namespace. But RTLD_NOLOAD was forgotten to check, and
with that flags nothing gets loaded into auditing namespace, so dlmopen()
should succeed and return the handle for auditing object.

Patch2 adds dlload_audit_module() function and a test-case for it.

Stas Sergeev (2):
  elf/dl-open: fix audit wrt RTLD_NOLOAD [BZ #30127]
  dlfcn,elf: impl dlload_audit_module [BZ #30127]
