unictype: avoid undefined left-shift behavior
* lib/unictype/bidi_of.c (uc_bidi_class): Building libunistring with
gcc's -fsanitize=shift and running its tests triggered:
unictype/bidi_of.c:43:60: runtime error: left shift of 40167 by 16 \
places cannot be represented in type 'int'
Cast LHS to 'unsigned int' after integer promotion.
* lib/unictype/categ_of.c (lookup_withtable): Likewise.
* lib/unictype/joininggroup_of.c (uc_joining_group): Likewise.
