This commit does the following two things:
1. Changes the Haskell package used in the extraDependencies test from
releaser to conduit. The reason for this is that conduit is more
of a "core" package in Haskell, and it is more likely to always be
working. (If conduit is not compiling, then large chunks of Hackage
won't be working.)
2. Tighten up the GHCi test to actually use the package from
extraDependencies. It appears that GHCi can fail to import the
package from extraDependencies, and that doesn't cause GHCi to
return an error code, which means the test isn't actually testing
anything.
This new change makes it so that if the package from
extraDependencies is actually not included for some reason, then
this shellFor test should fail.

This commit adds `pkgs.test.cross.sanity`, which is meant to be a
carefully curated list of builds/packages that tend to break when
refactoring our cross-compilation infrastructure.
It should strike a balance between being small enough to fit in
a single eval (i.e. not so large that hydra-eval-jobs is needed)
so we can ask @ofborg to check it, yet should have good examples
of things that often break. So, no buckshot `mapTestOnCross`
calls here.
Makes overrideAttrs usable in the same way that `override` can be used.
It allows the first argument of `overrideAttrs` to be either a function
or an attrset, instead of only a function:
hello.overrideAttrs (old: { postBuild = "echo hello"; })
hello.overrideAttrs { postBuild = "echo hello"; }
Previously only the first example was possible.
