fwupd: fix configuration on aarch64

The fwupd service was failing on aarch64 with:

fwupd: Failed to load engine: Failed to load remotes: failed to load /etc/fwupd/remotes.d/dell-esrt.conf: No such file or directory

The /etc/fwupd/remotes.d/dell-esrt.conf symlink existed but it pointed to a non-existent file.
