Sebastian Wick e07a5b5ac0 dir: Use fd-based traversal for marker files in deploy directories ...

The paths up to files/ are not attacker-controlled, and
g_file_replace_contents with G_FILE_CREATE_REPLACE_DESTINATION already
replaces symlinks rather than following them, so this is not a security
fix. The only reason why is that the file is in the root of the attacker
controlled directory.

This is a bit subtle, so lets do the right thing and concistently use
fd-relative operations when doing anything inside attacker/app
controlled directories.
