fastjar: Small _chsize/ftruncate fix

[Bryce McKinlay]

Michael Koch pointed out that fastjar could try to use both _chsize and 
ftruncate if a platform had both of these defined. This patch ensures we 
only ever use one. I'm checking it in.

    * jartool.c (main): Ensure that only one of ftruncate and _chsize
    is used.
