ocamlPackages.faraday: 0.5.0 -> 0.7.0

(cherry picked from commit 5f4bf24)

New android ndk (18) now uses clang. We were going through the wrapper
that are provided. This lead to surprising errors when building.
Ideally we could use the llvm linker as well, but this leads to errors
as many packages don’t support the llvm linker.

this isn’t useful any more because the ndk we use no longer supports it.

This results in a simpler service unit which doesn't first have to
start a shell:

  > cat /nix/store/s95nsr8zbkblklanqpkiap49mkwbaq45-unit-alertmanager.service/alertmanager.service
  ...
  ExecStart=/nix/store/4g784lwcy7kp69hg0z2hfwkhjp2914lr-alertmanager-0.16.2-bin/bin/alertmanager \
    --config.file /nix/store/p2c7fyi2jkkwq04z2flk84q4wyj2ggry-checked-config \
    --web.listen-address [::1]:9093 \
    --log.level warn
  ...

alertmanager: 0.15.3 -> 0.16.2
