Postfix virtual map fix

[Larry G. <List@ISComp.com>]

Hi All,

Attached is a text file outlining a modification to the
get_current_value() subroutine in postfix-lib.pl.  I could not find a way to
make postconf identify the virtual map.  Instead, I used the value
identified in $config_dir/main.cf.  I believe that main.cf is common for all
platforms and $config_dir will provide the proper path differing platforms.

Ramblings --
I don't know what the best way is to identify configuration files like this
one.  As the new version of Postfix changed the virtual maps and essentially
broke postconf, future updates to Postfix could eventually cause the same
type of problem.  A module I have been writing breaks out the file paths in
the module config.  However it is not dynamic enough yet to understand the
multiple map types.

Constructive thoughts, comments, or feedback are most welcome.
