Change Details

This is a partial backport of electrum#7926 and electrum#8310 and https://github.com/spesmilo/electrum/commit/d8abab34d81a1c67b23f9c408770690f538417ed The rustc version in Debian Buster is not recent enough to compile `cryptography`, so drop the `rustc` and `cargo` apt dependencies and don't compile `cryptography`. From https://cryptography.io/en/latest/installation/#rust > On most Linux distributions, the latest version of pip will be able to install a binary wheel, so you won’t need a Rust toolchain. Note that cryptography is not directly used in Electrum ABC, it is pulled into the release by the `dnspython` dependency. See https://github.com/EchterAgo/Electron-Cash/commit/a8c55d21ef236d738b6e2a9fb12c5cbe9c9ac9c3 This commit was only partially backported (I kept `dnspython[DNSSEC]` rather than changing it to `dnspython` in requirements.txt), so specifying the dependency on `cryptography` was actually never needed before, but now it is.
