David Runge authored.gitlab-ci.yml: Use environment variables to override the build settings offered by the build-host.sh script. Lower the RAM usage of the builds to 3072. Lower the COW space used by archiso to 2GiB. Remove dependency on libisoburn in the `before_script` section of the build target (libarchive and util-linux have replaced this requirement). Use size units in accordance with upstream documentation. Use the new name of the build's metrics file. Fixes #134

.gitlab/ci/build-host.sh: Change all script-local variables to lower-case and make some of them overridable using environment variables (by providing defaults). Break down overly long commands by splitting them into a list of strings. Use local variables where possible. Change `main()` to use rsync instead of cp to copy the project to the build location more generically. Change `main()` to use rsync instead of cp to copy the build artifacts on the VM from the project's build directory to the output. Remove all unnecessary `function` keywords for function declarations. Replace the dependency on libisoburn's `xorriso` with libarchive's `bsdtar` and util-linux's `blkid` in `prepare_boot()`. Add `print_section_start()` and `print_section_end()` to reduce code duplication and error potential when printing lines for gitlab's collapsible sections (https://docs.gitlab.com/ee/ci/jobs/#custom-collapsible-sections). Document the script's behavior and expectations. Document the understood environment variables and add links to documentation on understood units (in case of size units).

.gitlab/ci/build-inside-vm.sh: Add `print_section_start()` and `print_section_end()` to remove code duplication when printing gitlab collapsible sections (https://docs.gitlab.com/ee/ci/jobs/#custom-collapsible-sections). Document further script dependencies. Remove the temporary directory base (located in the project directory) instead of only the tempdir. Simplify setting file and directory ownership when running with sudo, by only doing it once, recursively on the output directory. Make the script's output more verbose by using verbose flags for removal, ownership changes and zsyncmake actions and by displaying e.g. created metrics and checksum files. Change `create_metrics()` to output to a `metrics.txt` by default. Change `create_checksums()` to create the checksums relative to the files.
