Issue #3249605: Color module breaks garland because of recent change in 7.x

Closes #3249605

Recent change in 7.x at 248892a6 causes style.css to get created with incorrect #000000's in place of the proper value.

To see this simply change garland's scheme to anything other than blue lagoon, e.g. ash, then visit the home page and look at the sidebar. The lower half is messed up.

When $normalize is TRUE, by definition the output is going to be a float between 0 and 1, so int'ing it makes it 0.
