fsck: report integer overflow in author timestamps
When we check commit objects, we complain if commit->date is
ULONG_MAX, which is an indication that we saw integer
overflow when parsing it. However, we do not do any check at
all for author lines, which also contain a timestamp.
Let's actually check the timestamps on each ident line
with strtoul. This catches both author and committer lines,
and we can get rid of the now-redundant commit->date check.
Note that like the existing check, we compare only against
ULONG_MAX. Now that we are calling strtoul at the site of
the check, we could be slightly more careful and also check
that errno is set to ERANGE. However, this will make further
refactoring in future patches a little harder, and it
doesn't really matter in practice.
For 32-bit systems, one would have to create a commit at the
exact wrong second in 2038. But by the time we get close to
that, all systems will hopefully have moved to 64-bit (and
if they haven't, they have a real problem one second later).
For 64-bit systems, by the time we get close to ULONG_MAX,
all systems will hopefully have been consumed in the fiery
wrath of our expanding Sun.

t1450: the order the objects are checked is undefined
When a tag T points at an object X that is of a type that is
different from what the tag records as, fsck should report it as an
error.
However, depending on the order X and T are checked individually,
the actual error message can be different. If X is checked first,
fsck remembers X's type and then when it checks T, it notices that T
records X as a wrong type (i.e. the complaint is about a broken tag
T). If T is checked first, on the other hand, fsck remembers that we
need to verify X is of the type tag records, and when it later
checks X, it notices that X is of a wrong type (i.e. the complaint
is about a broken object X).
The important thing is that fsck notices such an error and diagnoses
the issue on object X, but the test was expecting that we happen to
check objects in the order to make us detect issues with tag T, not
with object X. Remove this unwarranted assumption.
