mail/sympa now obeys hier!

[Chris Rees]

Hi all,

I've restructured the installation dirs for mail/sympa so we no longer
have a nasty /usr/local/sympa directory.

I'm asking for anyone to test the update as well as me -- I haven't
found any problems but if there's anything major I need to fix it
before it goes for committing!

It also removes a superfluous dependency (thanks to Igor Zabelin).

Thanks,

Chris
