genprotimg/boot: avoid the deletion of .lds files by using .SECONDARY

Browse Source 
Avoid the deletion of the intermediate
`(stage3a|stage3b|stage3b_reloc).lds` files by adding them to the
special built-in target `.SECONDARY` as prerequisites. This way they're
declared as intermediate files that should never be deleted
automatically. [1]
