sections.h/ranges.h/tablesh: change alignment to safe conservative values

The alignment values come from include/asm-generic/vmlinux.lds.h
through lessons picked up from STRUCT_ALIGN ALIGN_FUNCTION.

Note that his doesn't work though ! Make record of this and
make the respective functional changes next. Deciding how we
align can then be punted to the community.
