ci: dont use hardcoded project name

Not everyone's github project is "selinux" so use the projects
name, as derived from TRAVIS_BUILD_DIR. TRAVIS_BUILD_DIR is
the absolute path to the project checkout on disk, so the
basename should be sufficient. The script that runs in the KVM
environment also needs to be updated where it can find the
selinux project code, so we pass it in through an env variable
in the ssh command.

Tested on Travis CI here:
