elf: Signal LA_ACT_CONSISTENT to auditors after RT_CONSISTENT switch
Auditors can call into the dynamic loader again if
LA_ACT_CONSISTENT, and those recursive calls could observe
r_state != RT_CONSISTENT.
We should consider failing dlopen/dlmopen/dlclose if
r_state != RT_CONSISTENT. The dynamic linker is probably not
in a state in which it can handle reentrant calls. This
needs further investigation.
