Check sh_type/sh_flags/sh_addralign/sh_entsize when copying sh_link/sh_info
When copying the sh_link and sh_info fields in stripped section headers,
we also check if the sh_type, sh_flags, /sh_addralign and sh_entsize
fields of the output section match the output. Since --only-keep-debug
turns all non-debug sections into SHT_NOBITS sections, the output
SHT_NOBITS type matches any input type.
