Use bfd_get_32 and bfd_put_32 to access ch_type

The ch_type field in Elf64_External_Chdr is 4 bytes.  We should use
bfd_get_32 and bfd_put_32 to access it.

	* bfd.c (bfd_update_compression_header): Use bfd_put_32 on
	ch_type.
	(bfd_check_compression_header): Use bfd_get_32 on ch_type.
	(bfd_convert_section_contents): Use bfd_get_32 and bfd_put_32
	on ch_type.
