Fix compiler warnings. The warnings can result in a broken build.
This patch fixes warnings such as:
In file included from /usr/include/glib-2.0/glib.h:111,
from ../tests/plugin/syscall.c:13:
../tests/plugin/syscall.c: In function ‘print_entry’:
/usr/include/glib-2.0/glib/glib-autocleanups.h:28:3: error: ‘out’ may be
used uninitialized in this function [-Werror=maybe-uninitialized]
g_free (*pp);
^~~~~~~~~~~~
../tests/plugin/syscall.c:82:23: note: ‘out’ was declared here
g_autofree gchar *out;
^~~
