Andriy Gapon 6014c8de1d rtld: eliminate double call to close(2) that may occur in load_object ...

The second close(2) call resulted in heisenbugs in some multi-threaded
applications where e.g. dlopen(3) call in one thread could close a file
descriptor for a file having been opened in other thread concurrently.

My litmus test for this issue was an openoffice.org build.
