virt: Drop ATTRIBUTE_UNUSED for virt_eventloop_timeout_cb

ATTRIBUTE_UNUSED seems to be never was a public part of the libvirt interface
and leads to the following issue with recent libvirt versions were
ATTRIBUTE_UNUSED has been renamed to G_GNUC_UNUSED:

src/virt.c:2209:49: error: expected ';', ',' or ')' before 'ATTRIBUTE_UNUSED'
 2209 | static void virt_eventloop_timeout_cb(int timer ATTRIBUTE_UNUSED,
      |                                                 ^~~~~~~~~~~~~~~~

src/virt.c:2222:26: error: 'virt_eventloop_timeout_cb' undeclared (first use in this function)

src/virt.c:2222:26: note: each undeclared identifier is reported only once for each function it appears in

Drop ATTRIBUTE_UNUSED here as there is little use from it.
