Subject: [PATCH] unicode: add MODULE_DESCRIPTION() macros

Currently 'make W=1' reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in fs/unicode/utf8data.o
WARNING: modpost: missing MODULE_DESCRIPTION() in fs/unicode/utf8-selftest.o

Add a MODULE_DESCRIPTION() to utf8-selftest.c and utf8data.c_shipped,
and update mkutf8data.c to add a MODULE_DESCRIPTION() to any future
generated utf8data file.

Signed-off-by: Jeff Johnson <quic_jjohnson@...cinc.com>
---
Note that I verified that REGENERATE_UTF8DATA creates a file with
the correct MODULE_DESCRIPTION(), but that file has significantly
different contents than utf8data.c_shipped using the current:
https://www.unicode.org/Public/UNIDATA/UCD.zip
