stdlib: add missing stdc_rotate_right_ull alias when builtin is available

When __builtin_stdc_rotate_right is supported, glibc defines type-specific
aliases for several unsigned integer types (uc, us, ui, ul), but omits the
unsigned long long variant. This leads to an inconsistency between the
builtin-backed path and the generic fallback, where unsigned long long
is handled.

Add the missing stdc_rotate_right_ull macro mapping to
stdc_rotate_right(__x, __n) to complete the set of type-specific helpers
and ensure consistent API coverage across all supported unsigned integer
types.

No functional change for existing users; this only exposes the expected
alias for unsigned long long.
