Always use align_size as pr_datasz for GNU_PROPERTY_STACK_SIZE
For GNU_PROPERTY_STACK_SIZE, pr_datasz is the same as align_size, which
is 8 bytes for 64-bit ELF binaries and 4 bytes for 32-bit ELF binaries,
Use align_size as pr_datasz for GNU_PROPERTY_STACK_SIZE to convert
.note.gnu.property section.
