recovery: Fix the configuration of default_backup_format

I believe that this was missed (and therefore broken) in this commit:

commit a46e1bd7b32dc3ab660518a1aeab2f99d1ec518b

    Define paths for recovery settings files in a separate header

    Also, use get_primary_storage_path() to define the locations of .no_conf
    .many_confirm, and .hidenandroidprogress instead of hard-coding /sdcard/
