Release: Avoid dependency on libudev in OpenOCD

After commit "904e203 Release: Build libusb for Linux builds as well" libusb
was built locally for OpenOCD for Linux instead of using libusb from system
packages. This introduced dependency on libudev.so.0 present in RHEL/CentOS
6 systems, but absent in RHEL/CentOS 7, which has libudev.so.1.  To avoid
this dependency libusb should be built without udev support.
