bootstd: Provide an option to scan any partition

Browse Source 
By default, if a boot partition is found, no further partitions are
scanned on the same media.

This can be inconvenient in the case where there is an EFI
boot-partition present (mounted as /boot/efi), but extlinux is being
used to boot (e.g. mounted as /boot).

Provide a -p flag for 'bootflow scan' to allow any partition to be
scanned.
