Since this code path was recently converted to check for a NULL value,
it now behaves exactly like git_config_string(). We can shorten the code
a bit by using that helper.
Note that git_config_string() takes a const pointer, but our storage
variable is non-const. We're better off making this "const", though,
since the default value points to a string literal (and thus it would be
an error if anybody tried to write to it).

An observant reader may notice that this means duplicate config like:
[core]
checkRoundTripEncoding = foo
checkRoundTripEncoding = bar
will leak the string for "foo". That is true before this patch, too, and
is true of all callers of git_config_string(). I'm going to punt on that
for now, and look into it as a separate series.
