  modinfo prints an error message if modules.builtin.bin is missing

Bug description:
  Running a simple "update-initramfs -u" in a system with kmod version
  26+20191223-1ubuntu1 (from focal-proposed)

  will result into a bunch of:

  depmod: ERROR: ../libkmod/libkmod.c:515 lookup_builtin_file() could
  not open builtin file
  '/var/tmp/mkinitramfs_FLkEYb/lib/modules/5.4.0-14-generic/modules.builtin.bin'

  errors. That happens because:

  modinfo prints an error message if modules.builtin.bin is missing and
  it was fixed upstream (Debian) in:

  commit 835d584
  Author: Ben Hutchings <ben at decadent.org.uk>
  Date:   Sat Jan 18 15:44:32 2020

      mkinitramfs: Copy modules.builtin.bin into initramfs

      modinfo now prints an error message if modules.builtin.bin (created
      by depmod) is missing.  Copy it in early if it's present.

      Closes: #948257
      Signed-off-by: Ben Hutchings <ben at decadent.org.uk>
