ovs-dev.py: allow current directory to be used as the working directory

Rather than forcing a single ovs source tree under ~/ovs, this
change supports invoking the script from the root of any
ovs source tree as the working source tree. If the script is invoked
from a directory not recognized as OVS source tree, ~/ovs will
then be used.
