Add #ifdef __redox__ path to drmGetDeviceFromDevId() that mirrors the
working drmGetDevice2() Redox implementation. On Redox there is no
/dev/dri/ directory — DRM devices are accessed via /scheme/drm/card0.
The patch constructs a drmDevice with both PRIMARY and RENDER nodes
pointing to /scheme/drm/card0, since the redox-drm scheme serves both
roles through a single endpoint.
Also fixes drmParseSubsystemType() to return DRM_BUS_PCI on Redox.
Fix P3 patch paths (strip local/recipes/libs/libdrm/source/ prefix
from diff headers so patches apply correctly during repo fetch).
