Fix NIfTI-surface connection

[tsalo]

Closes none, but addresses an issue reported in https://neurostars.org/t/xcp-d-some-connections-were-not-found/30667.

This bug arises when users (1) provide derivatives with mesh files, (2) enable abcc-qc, and (3) enable NIfTI processing. Because the mesh files are available and abcc-qc is enabled, the surface-processing workflow is enabled (though without normalization to fsLR because --warp-surfaces-native2std isn't enabled), but the BOLD post-processing workflow doesn't use the post-processed surfaces.

This bug should affect versions 0.8.0 - 0.10.rc1, although it might affect earlier versions.

Changes proposed in this pull request

• Only pass midthickness files to the BOLD post-processing workflow if CIFTI processing is enabled.
