    Fix build
    
    An accidentally typed character in a translation broke it.
    
    http://build.gnome.org/continuous/buildmaster/builds/2017/03/11/0/build/log-gnome-shell.txt
    
    gl.po:632: 'msgstr' is not a valid JavaScript format string, unlike
    'msgid'. Reason: In the directive number 2, the character '$' is not a
    valid conversion specifier.
