Install hidden galaxy data files (e.g. .travis.yml) (#56005)

The package_data globs in setup.py were missing the necessary glob
to install:

galaxy/data/default/.travis.yml

A Python glob pattern will not by default match a hidden file
(i.e. a file basename beginning with a dot). If you want a glob
to pick up a hidden file in a directory you must explicitly specify
a glob pattern with "/.*".
