revert "fs/binfmt_elf: fix PT_LOAD p_align values for loaders"

Commit 925346c ("fs/binfmt_elf: fix PT_LOAD p_align values for
loaders") was an attempt to fix regressions due to 9630f0d
("fs/binfmt_elf: use PT_LOAD p_align values for static PIE").

But regressionss continue to be reported:

  https://bugzilla.kernel.org/show_bug.cgi?id=215720
  https://lkml.kernel.org/r/[email protected]

This patch reverts the fix, so the original can also be reverted.
