linux/export: Fix alignment for 64-bit ksymtab entries
An alignment of 4 bytes is wrong for 64-bit platforms which don't define
CONFIG_HAVE_ARCH_PREL32_RELOCATIONS (which then store 64-bit pointers).
Fix their alignment to 8 bytes.
Fixes: ddb5cdbafaaa ("kbuild: generate KSYMTAB entries by modpost")
