hack/build-go.sh --use_go_build would fail because e2e.test was not being
excluded from the set of things that we were "go build"ing
Instead of walking all binaries, only walk static and nonstatic

Go 1.4 added the -o flag to the "go test" command as well as support for
the TestMain() function, so we must work around these not existing in
Go 1.3.
The version of readlink on OS X does not have the -f flag - so we'll
just skip canonicalizing the path.
This commit deletes cmd/e2e and updates hack/ginkgo-e2e.sh to use the
'ginkgo' command instead. All logic from cmd/e2e/e2e.go and
test/e2e/driver.go have been combined into the new file
test/e2e/e2e_test.go.
The test tarball now includes a built version of the test/e2e test
binary, which includes all tests under test/e2e. This was accomplished
by updating the build scripts to use 'go test -c' when a target name
ended with '.test', and adding a dependency on test/e2e/e2e.test.
This prebuilt test binary is passed to the Ginkgo runner in
hack/ginkgo-e2e.sh. In a future change, we can add support to run
Ginkgo against the source tree if it is available.
This change is generally intended to have no externally visible changes,
aside from the following caveats:
- The -t/--tests flag has been removed
- Calling cmd/e2e/e2e directly obviously won't work, but that was never
intended to be supported anyway
- If the GINKGO_PARALLEL environment variable is set to y, then ginkgo
will run test specs in parallel. (Currently defaults to n, since some
tests are broken in this mode.)
Additionally, several tests which made poor assumptions about cwd or
used testContext before it had been set have been fixed.
