Bug description:
[Impact]
* Users cannot open a hyperlink in a PDF opened with evince when the default
browser is a snap.
* The fix creates a snap_browsers abstraction on AppArmor which can be used
in a transition for when the browser is executed. The snap_browsers abstraction
provides the minimal amount of permissions required to execute a browser
provided through snaps. This is a workaround since AppArmor currently does not
provide mediation/filtering on enhanced environment variables.
[Test Plan]
* Make sure the default browser is provided through the snap store.
* Open a PDF that contains a hyperlink using evince and click on the URL.
* The browser should open the requested URL.
[Where problems could occur]
* If the browser or snap core update to have new requirements for
opening a browser, then the current policy could become obsolete and
will need to be updated again.
