Ensure that compressed sections that have an ELF compression header structure at the start are correctly aligned.
PR 26428
bfd * bfd.c (bfd_update_compression_header): Also set the sh_addralign
field in the ELF header of the compressed sections.
ld * testsuite/ld-elf/zlibbegin.rS: Update expected output.
* testsuite/ld-elf/zlibnormal.rS: Likewise.
