ioctl: collect finfo just before decoding ioctl command
This way finfo can be used as hints for decoding ioctl commands.
* src/defs.h (get_finfo_for_dev): New declaration.
(printfd_with_finfo): New inline function - a thin wrapper around
printfd_pid_with_finfo.
* src/util.c (get_finfo_for_dev): Remove static modifier to
make it reusable the ioctl syscall decoder.
(SYS_FUNC(ioctl)): Call get_finfo_for_dev and printfd_with_finfo
instead of calling printfd.
