    Simplify windows-nat.c:windows_make_so #ifdefery
    
    There are two separate #ifndef __CYGWIN__/#else/#endif sections in the
    windows_make_so function with 3 lines of shared code separating them.
    I find this makes the code harder to understand than necessary.
    AFAICS, there is no reason those three shared lines need to be after
    the first #ifdef block.  There is no early return, nor are 'load_addr'
    nor 'name' modified.
    
    This commit moves that shared code to the top of the function, and
    then combines the two #ifndef sections.
