[gegl] noise-cell: Use f suffix for float constants.

[Daniel Sabo <daniels src gnome org>]

commit 1fb0a80f236d8ed75146e57e568b19ff1d906d99

    noise-cell: Use f suffix for float constants.
    
    Unsuffixed literal has type double (taken from c99 specs).
    Fixes clang warnings:
    warning: double precision constant requires cl_khr_fp64, casting to single precision
