libsmb: Add name_status_lmhosts

Browse Source 
Don't ask... Oh, you did? :-)

Try to figure out a hosts' name from lmhosts. This is for a setup I've
come across where for several reasons kerberos and ldap were unusable
(very organically grown but unchangeable Solaris 10 installation with
tons of ancient libs that ./configure incorrectly finds and where tar xf
samba-4.5.3.tar takes 5 minutes...), so I had to fall back to compile
with --without-ads. Unfortunately in that environment NetBIOS was also
turned off, but the "winbind rpc only" code relies on name_status to
get a DC's name from its IP address for the netlogon calls. This walks
the local lmhosts file to scan for the same information.
