This is a followup to 2ca982ff41.
* gnu/bootloader.scm (warn-target-field-deprecation): New macro.
(<bootloader-configuration>)[target]: Add 'sanitize' property.
(%warn-target-field-deprecation): New procedure.
(bootloader-configuration-target): Define using 'define-deprecated'.
(bootloader-configuration-targets): Use
'%bootloader-configuration-target' rather than the deprecated one.
