Depending on the distro and the type of login attempt (e.g. ssh, local login) the `ut_type` value in `/var/log/btmp` is different. So far, the login dataset only responded to the rarer login type `7` (`USER_PROCESS`). The more common one (seems to be exclusively used on Fedora 29, but also used on Ubuntu 18.04 for failed SSH login attempts) is `6` (`LOGIN_PROCESS`) that we are currently ignoring. This changes the code to have a separate function to process UTMP records from btmp files that treats both `USER_PROCESS` and `LOGIN_PROCESS` the same. It also adds a unit test for failed logins including a btmp test file from Ubuntu 18.04 with three bad login attempts. (cherry picked from commit 94666a8)
