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
