When strace has no specialised decoder for a syscall (as in case of
splice), a generic decoder is used, and the latter just prints syscall
arguments in hex.

I've just implemented specialised decoders for splice, tee and vmsplice
syscalls (commit v4.6-148-gd99e48c).  You can try to build strace from git
HEAD and report back whether you like it better than you old packaged
version.
