livepatch: Tighten alignment checks.

The ELF specification mentions nothing about the sh_size being
modulo the sh_addralign. Only that sh_addr MUST be aligned on
sh_addralign if sh_addralign is not zero or one.

We on loading did not take this in-to account so this patch adds
a check on the ELF file as it is being parsed.
