samba: fix build on qemumips64 with musl

There is the same issue as for libldb, the header has conflicting defs
for unitptr_t. Fix it as done for the other recipe.

Fix
 /cmocka/cmocka.h:126:28: error: conflicting types for 'uintptr_t'
    typedef unsigned int uintptr_t;
                             ^~~~~~~~~
