Subject: [PATCH] ci/update-pinned.sh: import Nixpkgs relative to script

Paths within a --expr expression are relative to the script file,
while relative paths in NIX_PATH are relative to the caller's CWD.

We want the Nixpkgs import to be relative to update-pinned.sh itself,
so that it does not matter where it's executed from.

See https://github.com/NixOS/nixpkgs/issues/425551

(cherry picked from commit 37aac0fb06e2ca890d463b35af6d45bad44a9f91)
