icc: Introduce --name flag to load a built-in profile by name

Browse Source 
...instead of from a file.

For now, `--name=sRGB` is the only valid value, but more will
probably follow in the future.

Just `icc --name=sRGB` prints the built-in sRGB profile.

`icc --name=sRGB --reencode-to=file.icc` writes it to file.icc.
