uniname/uniname: Fix -Wformat-signedness warning

[Bruno Haible]

In GNU gettext, with gcc 13, I see this warning:

gettext-tools/gnulib-lib/uniname/uniname.c:295:42: warning: format '%d' expects 
argument of type 'int', but argument 3 has type 'ucs4_t' {aka 'unsigned int'} 
[-Wformat=]

This patch fixes it. The other patch fixes some comments.
