Fix build phase dependency warnings

Make sure to specify the build phase (e.g. building locale files)
input/output dependencies so they can be properly skipped during
incremental builds if the input files haven't changed. Previously some
of them were set to use dependency tracking, but with no input/output
specified, therefore triggering a warning as Xcode had to run them every
build.
