Remove unneeded locales from gfxboot data file

The gfxboot data file (bootlogo) installed by mandriva-gfxboot-theme
package contains translations for all known languages. However, if this
file is too big, this causes boot problems on some systems (bug #48688).
On Ones, since we know the languages that will be included on the live
cd, we can remove all the locales we don't need from the bootlogo file.
