fsck.c: add an fsck_set_msg_type() API that takes enums

Change code I added in acf9de4c94e (mktag: use fsck instead of custom
verify_tag(), 2021-01-05) to make use of a new API function that takes
the fsck_msg_{id,type} types, instead of arbitrary strings that
we'll (hopefully) parse into those types.

At the time that the fsck_set_msg_type() API was introduced in
0282f4dced0 (fsck: offer a function to demote fsck errors to warnings,
2015-06-22) it was only intended to be used to parse user-supplied
data.

For things that are purely internal to the C code it makes sense to
have the compiler check these arguments, and to skip the sanity
checking of the data in fsck_set_msg_type() which is redundant to
checks we get from the compiler.
