revert "fs/binfmt_elf: use PT_LOAD p_align values for static PIE"

commit aeb7923733d100b86c6bc68e7ae32913b0cec9d8 upstream.

Despite Mike's attempted fix (925346c129da117122), regressions reports
continue:

  https://lore.kernel.org/lkml/cb5b81bd-9882-e5dc-cd22-54bdbaaefbbc@leemhuis.info/
  https://bugzilla.kernel.org/show_bug.cgi?id=215720
  https://lkml.kernel.org/r/b685f3d0-da34-531d-1aa9-479accd3e21b@leemhuis.info

So revert this patch.
