Bug Description

Commit 3c825eb001d33bb6f2480c4f78df03aee4c40396 in the Gitlab upstream adds a field called `execpath` to the `aa_log_record` struct. This field was added in the middle of the struct instead of the end, causing an ABI break in libapparmor without a corresponding major version number bump. This commit landed between v4.0.3 and v4.1.0-beta1, and unfortunately, Oracular currently packages v4.1.0-beta1.

Thus, we need to land a bugfix patch to move the `execpath` field to the end of the struct ASAP to prevent an ABI break from making it into the Oracular release. The patch is attached below and is available as commit c86c87e8868c72e5ab2084b5bf783cd5ca800a9b in the Gitlab repo.
