wicd: wrapper env vars prefix -> postfix

Change PATH=$PATH:deps to PATH=deps:$PATH in the wicd wrappers, because
the latter is more deterministic; it prevents possibly wrong versions of
dependencies to sneak in from the environment.

Do the same for PYTHONPATH.
linux: Don't put the kernel version in meta
Unify the Linux kernel configurations

Having N different copies of the NixOS kernel configuration is bad
because these copies tend to diverge.  For instance, our 3.10 config
lacked some modules that were enabled in older configs, probably
because the 3.10 config had been copied off an earlier version of some
older kernel config.

So now there is a single kernel config in common-config.nix.  It has a
few conditionals to deal with new/removed kernel options, but
otherwise it's pretty straightforward.

Also, a lot of cut&paste boilerplate between the kernel Nix
expressions is gone (such as preConfigure).
