log_warn is much shorter and we already use log_err instead of log_error
so this is more consistent now.

These are the only open() calls missing the flag.

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.

Add two functions to enter/leave our VT object. This allows to
implement to expected behavior of automatically switching to the kmscon
when it is running on a new tty, and switching back to the tty we came
from when the program finishes. Presumably this behavior will be
controlled by a config variable or command line argument later on (like
Xorg's -novtswitch).
There's a bit of a subtlety in this because of VT_PROCESS. We need
permission from ourselves to switch in/out of out VT; this is done when
processing SIGUSR[12] in the eloop. We therefore must dispatch the loop
at least once after switching out. The usual case is demonstrated in
test_vt.c.

As long as we are run in a VT we need to correctly handle VT-switches to avoid
blocking the crtc/input.
This is copied from wayland-compositor demos and modified to fit to our needs.
