objcopy fuzzed pe out of memory

This occurs when attempting to read back a section from the output
file in _bfd_XX_bfd_copy_private_bfd_data_common.  The copy of the
section failed size sanity checking, thus it won't be written.

	* objcopy.c (copy_object): Return false if copy_section or
	copy_relocations_in_section fails.
