iPXE does not make stable releases[1]. The tag we were using was an
anomoly[2], and is from 2020.
The geniso script has been replaced with a generic genfsimg script
that works differently. There are no longer variables we can set to
tell it where to find isolinux.bin or ldlinux.c32, so we have to patch
the script. It'll look in the same place for both files.
The --preserve=mode modification doesn't seem to be necessary any more
— when it was introduced in 4d7bea7e5e ("ipxe: fix ISO build"), it
was required to make a working ISO with an embedded script. But my
ISO with an embedded script now works fine without that change.

For example BANNER_TIMEOUT can be overriden like:
```
ipxe.overrideArgs(old: {
enableOptions = old.enableOptions ++ [ "BANNER_TIMEOUT 100" ];
});
```

According to https://repology.org/repository/nix_unstable/problems, we have a
lot of packages that have http links that redirect to https as their homepage.
This commit updates all these packages to use the https links as their
homepage.
The following script was used to make these updates:
```
curl https://repology.org/api/v1/repository/nix_unstable/problems \
| jq '.[] | .problem' -r \
| rg 'Homepage link "(.+)" is a permanent redirect to "(.+)" and should be updated' --replace 's@$1@$2@' \
| sort | uniq > script.sed
find -name '*.nix' | xargs -P4 -- sed -f script.sed -i
```
imgtrust is needed to run netboot.xyz scripts.
ping is useful for testing network settings.
Also add HTTP option for clarity (it's already being built).
gcc5 enables additional warnings, causing the build to fail with
-Werror. The build could be fixed by specifically disabling errors
for `discarded-array-qualifiers` and `logical-not-parentheses` warnings,
but simply passing -Wno-error is more future proof.
