Allow a value of 'localhost' in the MPIR_proctable interface. I'd prefer it if this entry used hostnames but it's also allowed to include resolvable names which may not actually be hostnames.  This probably means there are cases where padb doesn't work, this commit adds in a hack for localhost which is probably the most common of these cases.
