For some reason valgrind thinks the iov array in ustcomm_send_fd
is used uninitialised. Add a suppression so this won't show as
an error.

This suppression doesn't work with libpthread here on my system. My lib
version is 2.11.1 but still not working. I've add --gen-suppresions=yes
to valgrind and libc is used instead of libpthread :
obj:/lib/libc-2.11.1.so
It is working fine. However, we will have a problem with different
version of libc so for this, valgrind supports wildcard * and ?
obj:/lib/libc-2.* (this works very well)
Thanks!
