Rename build to pipeline for status badges

First commit in probably 2, for resolve gitlab-org/gitlab-ce#15582. This
commit is renaming files and classes from build to pipeline. Also
wording is editted to pipeline. Given `pipeline` had more characters
than `build`, I've made the field a bit wider. The width now matchers
the one for the coverage badge, so they look nice when in a table
format, or in a list.

As soon as this commit is merged to master, and released, the build.svg
is deprecated, meaning that all users which already placed a badge
should update it. However, to make sure it keeps working tests are added
for this case.
