gnu: glibc: Add dependency on Gettext, to install the message catalogs.

This fixes a bug whereby the libc.mo files were not installed, and thus
translations of libc's messages were not available.

* gnu/packages/commencement.scm (gettext-boot0): New variable.
  (glibc-final)[native-inputs]: New field.
* gnu/packages/base.scm (glibc)[native-inputs]: Add GNU-GETTEXT.
