Typo in virtual_maps documentation

[Magnus Bäck <magnus@xxxxxxxxxxx>]

The following tiny patch fixes what must be a typo in the
documentation of the virtual_maps parameter, which was replaced
by virtual_alias_{maps,domains} in Postfix 2.0 and not 2.1.

  <p> Optional lookup tables with a) names of domains for which all
  addresses are aliased to addresses in other local or remote domains,
  and b) addresses that are aliased to addresses in other local or
! remote domains.  Available before Postfix version 2.0. With Postfix 2.1
  and later, this is replaced by separate controls: virtual_alias_domains
  and virtual_alias_maps. </p>
