kcms/region_lanuage: Also enable GLIBC when UBUNTU_LOCALE is set
e8eabb68 guarded glibc related code behind GLIBC_LOCALE. It changed it so it is now defined if either GLIBC_LOCALE_AUTO or GLIBC_LOCALE_GENERATED is defined. However Ubtuntu also needs this code and did use it before. Without it results in broken LANG variables.
