In https://github.com/openzfs/zfs/commit/658fb802 OpenZFS introduced a
new compatibility feature. This is accompanied by some default profiles
which are located in the $out output of the Nix derivation. However,
these compatibility profiles are used by both the zpool executable
located in $out and the libzfs library located in $lib. This
inadvertently creates a cycle, because zpool refers to $lib to link
against libzfs but libzfs refers back to $out for the compatibility
profiles.
There are two possible routes to rectify this problem:
1. Patch the zpool source code to not read the compatibility profiles
and adjust the build system to put them into the $lib output.
2. Simply remove the $out/$lib split.
Since no other derivation in nixpkgs refers to the $lib output
explicitly we opt for the latter, because this is also in accordance
with upstream.
`throw` aborts eval when the package is touched in inappropriate places. See
https://github.com/NixOS/nixpkgs/issues/109001 for an adverse instance of that.
ZFS now behaves like a regular broken package when it's, you know, broken.
It also still prints the helpful incompatibility notice when fully evaluated.

pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
I bring in autoreconfHook269 instead of overriding it in
all-packages.nix, so that when an unstable version of ZFS comes out
that supports autoconf 2.70, it can use the latest autoconf even if
stable ZFS still needs the old version.
sudo the package is not suid, so remove it from the PATH. Extend
PATH with $PATH to fetch sudo from the outer PATH. Move the generation
of `path` in to Nix, so the sed expression can use single quotes,
which prevents $PATH being interpolated at build-time.
Adding this patch makes zfs compile against 5.8-rc7 kernels.
