gsm_utils: call gnutls_global_init() as constructor
gnutls_global_init must be called at least once for gnutls < 3.3.0. It doesn't hurt calling it twice, except a reference counter is increased. gnutls >= 3.3.0 will call it automatic. Fixes: OS#2986 Change-Id: I241b6ae5aa8df13dd78f04658cf0953e9561c9e2
