tests: fix a memory in test_socket_unix_abstract_good

After build qemu with '-fsanitize=address' extra-cflags,
'make check' show following leak:

=================================================================
==44580==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 2500 byte(s) in 1 object(s) allocated from:
    #0 0x7f1b5a8b8d28 in __interceptor_calloc (/usr/lib/x86_64-linux-gnu/libasan.so.4+0xded28)
    #1 0x7f1b5a514b10 in g_malloc0 (/usr/lib/x86_64-linux-gnu/libglib-2.0.so.0+0x51b10)
    #2 0xd79ea4e4c0ad31c3  (<unknown module>)

SUMMARY: AddressSanitizer: 2500 byte(s) leaked in 1 allocation(s).

Call 'g_rand_free' in the end of function to avoid this.
