[svn-r29136] Added code to main routine of objcopy to close the FAPL fapl2
shortly before exit.

This in turn hides the property list management failure that 
is otherwise expressed on library shutdown when run with either
the split or multi file drivers.

Needless to say, this is a bandaid.  The actual cause of the 
problem must be found and dealt with.

Tested on Jam -- serial/debug/check-vfd
