feat: build in tempdir and move files on success (#82)

* feat: build in tempdir and move files on success

Before it would delete your outputs before starting the build. That
means miss-typing the command for example could lead to losing data.
This also creates separate folders for each type to avoid collision.

* fix: tempdir naming

this follows the convention set in the `_rootful_load_image` target.

* fix: delete output folder in clean target

* fix: move contents of temp build directory

This ensures a flatter folder structure, bib allready seem to ensure
there aren't any file name collisions.

output folder would look like this after building a raw and qcow2.

output
├── image
│   └── disk.raw
├── manifest-qcow2.json
├── manifest-raw.json
└── qcow2
    └── disk.qcow2

* fix: overwrite previous output directory

From conversations in https://github.com/ublue-os/image-template/pull/82
this is the wanted behaviour for this project.

* revert: overwrite previous output directory

This reverts commit 75448d72fa624cea01524d5651c926ae772460bf.

* chore(gitignore): ensure build directories are not showing up on diffs
