[2/2] git commit: Use user.signingkey for tag-signing.

[ke...@apache.org]

Use user.signingkey for tag-signing.

Rather than use UID require an explicitly-set key ID, following recommendations at [1].

[1] http://www.apache.org/dev/openpgp.html

Testing Done:
Tested with user.signingkey set and unset on local merged master.
