[PATCH BlueZ v3 2/2] tools/mgmt-tester: Fix formatter for size_t value

[Brian Gix <brian.gix@xxxxxxxxx>]

On 32 bit systems, sizeof macro doesn't always return (unsigned long),
and the %zu formatter specifically handles size_t.

Fix following error:

tools/mgmt-tester.c: In function ‘read_50_controller_cap_complete’:
tools/mgmt-tester.c:9124:58: error: format ‘%lu’ expects argument of type
‘long unsigned int’, but argument 2 has type ‘unsigned int’ [-Werror=format=]

 9124 |   tester_warn("Controller capabilities malformed, size %lu != %u",
      |                                                        ~~^
