This commit allows for the snap distribution of KeepassXC to self-manage native messaging manifests
This is done by making the binary aware of the snapd environment changes that currently prevent this.
Furthermore, the snap sandbox is expanded to the bare minimum needed to access these privileged files.
Please note if running a self-compiled / untrusted KeepassXC snap build (I.E, installed with --dangerous)
that you must manually run `sudo snap connect keepassxc:browser-native-messaging` to grant permissions.
This will work on all distributions that expose `/snap/bin/` - such as Ubuntu, Debian, etc.
For systems which don't provide `/snap/`, such as Fedora, follow instructions for enabling "Classic" snaps.
e.g., `sudo ln -s /var/lib/snapd/snap /snap`
