wayland: fix musl build issue

With musl C library, we see following build failure.

  src/scanner.c: In function 'find_enumeration':
  src/scanner.c:811:2: error: unknown type name 'uint'
    uint idx = 0, j;
    ^

uint is defined in <sys/types.h> header. It is usually included by <stdlib.h>
but in musl stdlib.h doesn't include it.

This patch adds upstream patch where uint32_t is used instead of uint.

Fixes:
