Subject: [PATCH] haskellPackages.ghc-settings-edit: avoid the use of filesets

This should be 0 rebuilds, except it fixes the installer tests, as
lib.filesets is somehow broken when combining chroot stores with
channel references (???).

Running nixosTests.installer.simple with this reverted will reproduce
the issue consistently.
