[libvirt PATCH 1/3] openvzDomainMigratePrepare3Params: correctly use hostname

[Ján Tomko]

In case no uri_in was supplied, we forgot to set the hostname
to the current hostname and formatted a useless uri_out.

src/util/glibcompat.h:57:26: error: ‘%s’ directive argument is null [-Werror=format-overflow=]
  57 | # define g_strdup_printf vir_g_strdup_printf
src/openvz/openvz_driver.c:2136:16: note: in expansion of macro ‘g_strdup_printf’
2136 |     *uri_out = g_strdup_printf("ssh://%s", hostname);
