    build: fix creating po files for new languages
    
    When the build dir was different from the source dir creating po files
    for new languages failed because the directories didn't exist yet.
    
    Explicitly add the srcdir for the po files to make it not check the
    build dir since po files are always in the srcdir.
    
    (cherry picked from commit a2446d68282a07d5271981290e33ebeb8e3ae364)
