Subject: pacman-key: Add --import and --import-trustdb

Currently, pacman-key allows the user to import their keys using the --add
option. However, no similar functionality exists for importing ownertrust
values.

The --import-trustdb option takes a list of directories and imports ownertrust
values if the directories have a trustdb.gpg database.

The --import option takes a list of directories and imports keys from
pubring.gpg and ownertrust values from trustdb.gpg. Think of it as a combination
of --add and --import-trustdb
