Philip Müller 54e0a1bbf1 templates: Properly disable the os-prober by default
This patch does the following:
 - really disables os-prober by default in the util/grub-mkconfig.in
   by setting GRUB_DISABLE_OS_PROBER to true,
 - fixes the logic in the util/grub.d/30_os-prober.in,
 - updates the grub_warn() lines.

Reason for the code shuffling in the util/grub-mkconfig.in:

  The default was GRUB_DISABLE_OS_PROBER=false if you don't set
  GRUB_DISABLE_OS_PROBER at all. To prevent os-prober from starting we
  have to set it by default to true and shuffle GRUB_DISABLE_OS_PROBER to
  code section, which is executed by the script. However we still give an
  option to the user to overwrite it with false, if he wants to execute
  os-prober after all.

Fixes: e3464147 (templates: Disable the os-prober by default)

All executable files in this directory are processed in shell expansion order.

  00_*: Reserved for 00_header.
  10_*: Native boot entries.
  20_*: Third party apps (e.g. memtest86+).

The number namespace in-between is configurable by system installer and/or
administrator.  For example, you can add an entry to boot another OS as
01_otheros, 11_otheros, etc, depending on the position you want it to occupy in
the menu; and then adjust the default setting via /etc/default/grub.
