./run_tests.sh --makemessages update English PO files only

Closes-Bug: #1224388

We don't need to update PO files of all languages.
PO files of languages other than English should be update by
importing translations from Transifex.

This commit changes "run_tests.sh --makemessages" only updates
English PO files. This makes a patch updating PO files shorter
and helps reviewers to check it.

modifies error message in adding security rule

Because the information on the type of input data
is outputted in "validate_ip_protocol" method,
I removed the information on the type and
modified error message.

At the same time, I make error messages translatables
in this file.
