Log: 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.
