elfloader: arm: fix alignment of AArch32

pagetables.

The 64 kiB alignment is a maximum requirement for a stage2
concatenated pagetable. See Table G5-4 in ARM DDI 0487I.a, page
G5-9186.

Note: Both comments at the top of the file as well as in line 85
say "64 kiB". 2^14 is unfortunately only 16 kiB.

Note2: This code is not executed on AArch64, because the
finish_relocation() function panics on AArch64. The latter always
takes the "shortcut" via continue_boot().
