lint: fix error [303,602,701,702]

[303] mktemp used in place of tempfile module
 [602] Don't compare to empty string
 [701] No 'galaxy_info' found
 [702] Use 'galaxy_tags' rather than 'categories'

This patch also changes the ansible log_path value via the
ANSIBLE_LOG_PATH environment variable in the travis configuration to
avoid warnings.

[WARNING]: log file at /home/travis/ansible/ansible.log is not writeable
