Update tox.ini bashate to test all bash scripts

Currently, the tox.ini file is only running bashate against files that
end in a .sh extension. However, many of the build tools do not have
an extension, and therefore don't have bashate executed against them.
This commit enhances the tox command to search for shell scripts
regardless of file extension.

The bashate ignore list has been updated to ignore all existing
warnings. Future updates can perform cleanup to address the
outstanding issues and remove items from the ignore list one by one.

The original check of .sh is maintained with a smaller ignore list, to
ensure new issues are not introduced.
