Title: Make InstallCommandTest faster.

# Motivation
`InstallCommandTest` builds PHP multiple times and takes very long time to finish, so we need to wait for a long time to get build status on Travis CI. After applying this PR, the time of running tests on Travis CI decreases from `15 min 15 sec` to `5 min 39 sec`.

# Solution
I've added `--jobs`option if we can know the number of CPU processor in `InstallCommandTest`.
