Improve exit statuses and error messages in pacman-key

Return codes from gpg commands are currently lost. This adds the functionality
of taking non-zero exit statuses from gpg. This includes error reporting for all
gpg commands that are run individually, run in a loop, and run through a pipe.

Includes the check_keyids_exist function which verifies a key exists locally
prior to attempted local manipulation of the key.

If a gpg command has a non-zero status, pacman-key will now exit with a non-zero
status. It will print a gettext error message of gpg's failure.
