In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

This enables mount to find lklfuse when mounting with the type
"fuse.lklfuse". With this fix, lklfuse can be used to mount filesystems
with NixOS filesystem options.
This is the same fix as has been applied to bindfs, mergerfs, and
apfs-fuse.
There is a pull request in the LKL repo adding firewall support:
https://github.com/lkl/linux/pull/431
It simply enables the appropriate options in the kernel config, since
the framework is already there.
It has not been merged yet, because enabling these options by default
would lead to bigger lkl binaries and an overall slowdown for all users.
However, since we can provide an opt-in variant with Firewall support,
there is no reason not to do it.
This is very useful for nftables rule checking without having access to
the kernel interface.
Bump lkl version to latest that includes merge of Linux 4.15 and fix for
an issue where cptofs wasn't returning failure when image size was too
small and file copying failed with:
error writing file: No space left on device
(see lkl/linux#427)
- Moves to a more recent kernel (4.10, I think ...)
- API break re the previous version
- cptofs: fix root directory copy
- add support for disks with custom ops
- add LKL_HIJACK_NET_QDISC to configure qdisc policy
- add LKL_HIJACK_SYSCTL to configure sysctl values
