Bump versions of charnames and Unicode::UCD after last patches

Bump versions of charnames and Unicode::UCD after last patches
(cherry picked from commit 529f008e1350d1b04e9f98427e8b2c8717a80712)

[Amended during the cherry-pick: charnames’ version is set to 1.071,
 not 1.08, as the 1.08 included with 5.13.1 has other changes.
 Unicode::UCD does not have that problem, as what 5.12.5 includes (as
 of the previous commit) is identical to what came with 5.13.1.]
