build: Make doc-po-update and doc-pot-update targets idempotent.
It used to be that the running the doc-po-update and doc-pot-update targets would redo the same work on every run. This change splits the problem in smaller chunks and specifies build dependencies in a way that outputs only get rebuilt when their inputs changed. * po/doc/local.mk (DOC_PO_FILES): Harmonize escapes. (POT_OPTIONS): Re-indent uniformly. (doc-po-update-%, doc-po-update-cookbook-%): Re-implement with... (make-update-po-files-rule): ... this new function. (TMP_POT_FILES): Remove variable. (%D%/%.pot, %D%/guix-manual.pot): New pattern rules. (doc-pot-update, doc-po-update): Adjust prerequisites accordingly.
