Helps: #1415
There is no guarantee that this function would not be called
concurrently. Particularly since flatpak_info_read was set to TRUE
before /.flatpak-info is actually read from disk, there is a potential
race where a second thread would return default values for the various
flags set from that file.
Fixes#2159
The flatpak-info file was moved to a different location a while
ago, we should read it from there instead of relying on the
compat symlink. One advantage is that this is a fixed, short
path, we don't have to construct one dynamically.

These are private helper functions that will be used in
the following commits to get information about whether
we are running in a flatpak sandbox, etc.
We allow the use of GTK_USE_PORTAL=1 in the environment
to force the use of portals. This can be useful for
testing and debugging portal interaction.
