Add Dockerfile for Astra Linux SE 1.8.1

[opomuc]

Mostly a copy-paste from Astra Linux 1.7.

Removed installation ofdh-systemd package since Astra 1.8 does not have it. debhelper and dh_systemd_enable/start are present.

No objections from my side.

@opomuc said that he is looking for different variants of his testing pipeline and this image is one of the variants. We agreed that the pull request shouldn't be merged until @opomuc's decision (or until someone else find it useful).
