* tests/virnettlscontexttest: fix memory leak on virnettlscontext test case.

* Detected in valgrind run:

==25667==
==25667== 86,651 (34,680 direct, 51,971 indirect) bytes in 10 blocks are
definitely lost in loss record 350 of 351
==25667==    at 0x4005447: calloc (vg_replace_malloc.c:467)
==25667==    by 0x4F1F515D: gnutls_init (gnutls_state.c:270)
==25667==    by 0x8053432: virNetTLSSessionNew (virnettlscontext.c:1181)

* How to reproduce?
% cd libvirt && ./configure && make && make -C tests valgrind
or
% valgrind -v --leak-check=full ./tests/virnettlscontexttest
