Subject: sna: udev integration depends on fstat and sys/stat.h

src/sna/sna_driver.c: In function 'sna_handle_uevents':
src/sna/sna_driver.c:759:2: error: implicit declaration of function 'fstat' [-Werror=implicit-function-declaration]

Also take the opportunity to include udev support in the configure
summary.
