selftest:Samba3: use the correct NSS_WRAPPER_HOSTNAME

Browse Source 
The value of NSS_WRAPPER_HOSTNAME needs to match value
we put into the NSS_WRAPPER_HOSTS file.

We had a mismatch of
idmapridmember.samba.example.com
vs.
idmapridmember.addom.samba.example.com

This causes getaddrinfo() in nss_wrapper to fallback to
the libc version, which talks to a dns server.
It's not clear if recent glibc code will reach resolve/socket wrapper.
So it's not unlikely that idmapridmember.samba.example.com will
be passed via the internet, which causes delays up to 20 seconds.
