[PATCH] speakup: Fix compilation in some build environments

[Nikita Travkin]

A compilation error may occur if the host CC doesn't have u_char
defined:

  HOSTCC  drivers/accessibility/speakup/makemapdata.o
In file included from ../drivers/accessibility/speakup/makemapdata.c:15:
../drivers/accessibility/speakup/utils.h: In function 'hash_name':
../drivers/accessibility/speakup/utils.h:57:9: error: unknown type name 'u_char'; did you mean 'char'?
   57 |         u_char *pn = (u_char *)name;
      |         ^~~~~~
      |         char

Fix this by using "unsigned char" instead.

Fixes: 6a5c94d92699 ("speakup: Generate speakupmap.h automatically")
