Sebastian Wick 924bdc9b3d run: Harden ensure_data_dir and /var setup against symlink attacks
Replace path-based flatpak_mkdir_p calls in flatpak_ensure_data_dir
with glnx_chase_and_mkdirat(RESOLVE_NO_SYMLINKS) to prevent an app
from replacing subdirectories of its data dir with symlinks between
runs and having them followed during the next sandbox setup.

In flatpak_run_setup_base_argv, replace path-based --bind args for
the app cache/data/config/tmp directories with --bind-fd using fds
obtained via glnx_chaseat(RESOLVE_NO_SYMLINKS), preventing both
symlink following and TOCTOU races when setting up these bind mounts.
