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
```
uwimap was shipping an `include/unix.h` file that would be falsely
detected by many applications (e.g. php and its modules). Due to that
file we got hacks like 8c125c0c74.
This also adds some previously missing files that would normally be
installed by uwimap (linkage.c, osdep/unix/*.h, …)
The following parameters are now available:
* hardeningDisable
To disable specific hardening flags
* hardeningEnable

other wrappers, builders or setup hooks.

* fortify
* stackprotector
* pie (disabled by default)
* pic
* strictoverflow
* format
