Makefile: add "po-update" rule to update po/XX.po

Since there is no longer a "po/git.pot" file in tree, a l10n team leader
has to run several commands to update their "po/XX.po" file:

    $ make pot
    $ msgmerge --add-location --backup=off -U po/XX.po po/git.pot

To make this process easier, add a new rule so that l10n team leaders
can update their "po/XX.po" with one command. E.g.:

    $ make po-update PO_FILE=po/zh_CN.po
