Oleh Nykyforchyn 0c23d26fb8 xserver: os/log.c: ignore alternate forms in log formats ...

This patch fixes Xserver crashes when evdev or synaptics input drivers are used.
These (and maybe other) driver use alternate forms "%#..." in formats for
xf86IDrvLogVerb() function, which in turn uses signal-safe vpnprintf().
The last function does not recognize alternate forms and exits abnormally, which
causes Xserver to crash. The patch make vpnprintf() to ignore alternate forms.
