Increase size of error printing char buffers

[peci1]

The error message at

camera1394/src/nodes/dev_camera1394.cpp

Lines 197 to 200 in abc1950

	CAM_EXCEPT(camera1394::Exception,
	"Could not initialize dc1394_context.\n"
	"Make sure /dev/raw1394 exists, you have access permission,\n"
	"and libraw1394 development package is installed.");

is longer than 100 chars, and GCC 8.3 started figuring this out and reports a warning about the buffer being too small (the size computed by gcc is 165 chars).
