Improve the internal filesystem detection, with these changes we
can reuse this code elsewhere and be more efficient - other areas
needing the filesystem knowledge can use this mapping strategies
adding a more precise and centralized code to that.
This patch also makes sure to keep tests and filesystem checks more
consistent.
When mounting we were assuming the /boot filesystem to always be
vfat, with this code now we can have /boot partitions with whatever
filesystem we support (for now: vfat, ext[2-4]).

We should not rely on these being present on the filesystem and
the space we use is minimal. On top of that, we need at a later stage
dynamically choose gpt or non-gpt MBR blocks depending on the device,
so we need both available no matter what.
Punch a hole so the bootloader can easily get the wanted_boot_mask
and decide whether the GPT or non-GPT mbr.bin is needed.
