gst: Add helper to fixate DMA_DRM caps

Browse source 
When support for modifier-aware DMA_DRM formats was added in f1b75fc6,
the translation between Pipewire parameters and Gstreamer caps was kept
compatible with the] non-DMA_DRM/legacy API by reporting format/modifier
combinations with linear or invalid modifier both as `format` and
`drm-format`.

In cases when a linear modifier ends up being negotiated, this, however,
resurts in non-fixated caps, preventing the negotiation to succeed.

Add a helper that allows to fixate such caps.
