fsck.h: re-order and re-assign "enum fsck_msg_type"

Change the values in the "enum fsck_msg_type" from being manually
assigned to using default C enum values.

This means we end up with a FSCK_IGNORE=0, which was previously
defined as "2".

I'm confident that nothing relies on these values, we always compare
them for equality. Let's not omit "0" so it won't be assumed that
we're using these as a boolean somewhere.

This also allows us to re-structure the fields to mark which are
"private" v.s. "public". See the preceding commit for a rationale for
not simply splitting these into two enums, namely that this is used
for both the private and public fsck API.
