ACCUMULO-4400 Best effort to reset gpg-agent cache

Make a best effort to reset gpg-agent cache, so that the signing key
will stay cached throughout the full duration of the release candidate
build, when created using build.sh

Limitations:
  1. This will force the password to be input at the beginning of the
     build.sh script, unless the user is using some persistent cache
     like gnome-keyring-daemon to manage one's key.
  2. If the user pauses at the prompts later in the script, for a long
     period of time, the cache could still expire during execution, even
     if the cache is reset at the start of the script.
  3. The build.sh script still presumes that gpg-agent is configured
     with a sufficiently large enough default-cache-ttl and
     max-cache-ttl values, so that the cache won't expire during the
     creation of the release candidate.
