bfd_cleanup for object_p 

The object_p (and archive_p, core_file_p) functions are not supposed
to have any target specific malloc'd memory attached to the bfd on
their return.  This should be obvious on a failure return, but it's
also true for a successful return.  The reason is that even though the
object_p recognises the file, that particular target may not be used
and thus the bfd won't be closed calling close_and_cleanup for the
target that allocated the memory.

It turns out that the object_p bfd_target* return value isn't needed.
In all cases except ld/plugin.c the target is abfd->xvec and with
ld/plugin.c the target isn't used.  So this patch returns a cleanup
function from object_p instead, called in bfd_check_format_matches to
tidy the bfd before trying a different target match.  The only cleanup
that does anything at this stage is the alpha-vms one.
