runtime: move osinit to Go

    
    This is a step toward updating libgo to 1.13.  This adds the 1.13
    version of the osinit function to Go code, and removes the
    corresponding code from the C runtime.  This should simplify future updates.
    Some additional 1.13 code was brought in to simplify this change.
