Revert "gnu: ucx: Update to 1.17.0."

This reverts commit 7c36577cde, which
broke unit tests running in the chroot build environment.

For instance, tests of ‘hdf5-parallel-openmpi’ would fail with:

Since /sys is unavailable in build environments, the list of available
TCP network interfaces cannot be obtained via /sys/class/net. This patch
provides alternative code that uses the SIOCGIFCONF ioctl to get the
names of the available TCP network interfaces.
Initially submitted at <https://github.com/openucx/ucx/pull/4462>.
