[PATCH 1/3] i18n: treat "make pot" as an explicitly-invoked target

From: Jonathan Nieder <jrnieder@gmail.com>

po/git.pot is normally used as-is and not regenerated by people building git, so it is okay if an explicit "make po/git.pot" always automatically regenerates it. Depend on the magic FORCE target instead of explicitly keeping track of dependencies.

This simplifies the makefile, in particular preparing for a moment when $(LIB_H), which is part of $(LOCALIZED_C), can be computed on the fly. It also fixes a slight breakage in which changes to perl and shell scripts did not trigger a rebuild of po/git.pot.

We still need a dependency on GENERATED_H, to force those files to be built when regenerating git.pot.

Mostly as you sent it, but I mentioned the missing script dependencies
in the commit message, too.
