flatpak 1.0.5 release.

There was a sandbox bug in the previous version where parts of the runtime /etc was not mounted read-only. In case the runtime was installed as the user (not the default) this means that the app could modify files on the runtime. Nothing in the host uses the runtime files, so this is not a direct sandbox escape, but it is possible that an app can confuse a different app that has higher permissions and so gain privileges.

Detailed changes:

• Make the /etc -> /usr/etc bind-mounts read-only.
• Make various app-specific configuration files read-only.
• flatpak is more picky about remote names to avoid problems with storing weird names in the ostree config.
• A segfault in libflatpak handling of bundles was fixed.
• Updated translations
• Fixed a regression in flatpak run that caused problems running user-installed apps when the system installation was broken.

In addition to upstream changes, this update also fixes a packaging issue and adds a missing dependency on p11-kit-server to fix accessing host TLS certificates.
