Currently, the initrd image is aligned to 8. This is problematic for
CoVE where the image is expected to be aligned at page granularity level.

Thus, align it to 4k. This can be done only if user requested a TVM.
However, initrd usually much bigger (in MBs at least). Thus, aligning
to a page for everything should not matter much.
