pactree: Make error message smarter in register_syncs()

Our error message used to be very unclear when the configuration file
could not be found:

    $ ./pactree -lsr gtk
    error: failed to register sync DBs

Instead, display an accurate message and include the file name:

    $ ./pactree -lsr gtk
    error: config file /usr/local/etc/pacman.conf could not be read

Also, move the error message inside register_syncs() to allow for
differentiating between different errors that might require a handler in
the future.
