gnu: commencement: Remove the tricky locale compatibility handling.

This is made unnecessary by the use of 'GUIX_LOCPATH'.

* gnu/packages/commencement.scm (locale-proof-package): Remove.
  (%boot5-inputs): Add on GLIBC-UTF8-LOCALES-FINAL.  This reverts parts
  of commit 28cbc58.
* gnu/packages/gawk.scm (gawk): Set 'GUIX_LOCPATH' instead of
  'LOCPATH'.
