Vagrant shared folder, at least on the default virtual box, does not
support the creation of the socket files. If one were to build OVS
under /vagrant, 'make check' would not work.
Out of tree builds can be used to work around this issue.
See Install.md for instructions.
Since out of tree builds requires a clean source tree, Vagrantfile can
not be a generated file. This commit removes Vagrantfile.in, commit
Vagrantfile instead.
