TST: add 32 bit travis tests

Implemented by setting up a chroot in the travis VM and moving all the
test logic, including bento build, to a single script.
This is still reasonable fast, about twice as slow as the normal tests.
When Travis updates to a newer OS it can be replaced by standard cross
compiling.

+  # e.g. running old test modules that were in the stable release but
+  # have been removed from master. (See gh-2765, gh-2768.)  Using 'pip
