Let pacman specify GnuPG's home directory.

GnuPG looks for configuration files and keyrings in its home directory.
For a user, that is typically ~/.gnupg.
This patch causes pacman to use /etc/pacman.d/gnupg/ as the default
GnuPG home.  One may override the default using --gpgdir on the command-line
or GPGDir in pacman's configuration file.
