HOSTER: .distignore included in builds despite being listed in .distignore

Bug: .distignore file is included in builds when using GitHub integration

When using Hoster with GitHub, the .distignore file itself is included in the build output even though it is listed in .distignore.

Steps to reproduce:

1. Create a plugin.

2. Link the plugin to a GitHub repository.

3. Create a build.

4. Inspect the contents of the generated build file.

Expected behavior:
All files listed in .distignore should be excluded from the build, including the .distignore file itself.

Actual behavior:
All files listed in .distignore are excluded except .distignore itself.
The .distignore file is present in the build, and when opened, it contains the original contents, including the reference to itself.

This happens on all builds.

Environment:
Hoster v1.3.3
