dyndbg: add source filename to prefix
Printing the line number without the file is of limited usefulness.
Knowing the filename also makes it also easier to relate the logged
information to the controlfile.
Example:
# modprobe test_dynamic_debug
# echo 'file test_dynamic_debug.c =pfsl' > /proc/dynamic_debug/control
# echo 1 > /sys/module/test_dynamic_debug/parameters/do_prints
# dmesg | tail -2
