[PATCH] resolv_wrapper: prevent RTLD_DEEPBIND if run with libasan

[swen]

Hi Andreas

thanks for your quick response.

I was trying to run some basic (samba) tests with the 2 sanitizers
enabled but was stopped right away with the DEEPBIND error.

After applying your updates and my 2 small additions that worked.
But now this even runs without the resolv_wrapper patch :-)

Not sure what went wrong on my system, but anyway.

So my intention was not to run resolv-wrapper code with the sanitizers
but more the main samba code.

Anyway, sorry for the noise !

Cheers Swen
