[frameworks/kdeclarative] src/qmlcontrols/graphicaleffects: graphicaleffects: Use "coord" input on lanczos.frag shader

Git commit 21e8ff76ed8316596a138eaa9853c8890a45e211 by Kai Uwe Broulik.

Pushed by broulik into branch 'master'.

graphicaleffects: Use "coord" input on lanczos.frag shader

Avoids a warning on the vertex output and fragment input names not matching up:

> Vertex output name 'coord' does not match fragment input 'texcoord'. This should
> be avoided because it causes problems with older GLSL versions.
