Currently, we set up our VT with SIGUSR1/2 signals and after that the user may connect the signal handlers to the eloop. However, if we receive a signal in between, the signal gets lost. Therefore, this simply merges the kmscon_vt_connect_eloop function into kmscon_vt_open as there is no obvious reason to split them. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com>
