Update flatpak and portals to latest versions

flatpak 0.99.1

This is the first pre-release before flatpak 1.0. This is considered feature-complete and we expect no features or major changes before 1.0, only bugfixes.

Note: There were some (minor) API changes in the FlatpakTransaction APIs that were added in 0.11.8, so please don't use the old version. (Note: I know of no user of this API).

Changes since last minor release:

• Ostree 2018.6 is required, and with this, the p2p code in flatpak is made non-optional.
• flatpak install/update/ininstall now lists all the operations that it will do and asks for confirmation before starting.
• In the above confirmation the permissions (new permissions for updates) are shown for all applications.
• The FlatpakTranscation API has a new ::ready signal that allows users to do similar confirmation prompts.
• P2P updates are more efficient
• system-wide installation uses less fsync calls so should installation should be faster.
• New ssh agent permissions allows granting an app ssh access.
