So if you're going to smash every single entry, why did you bother
doing a test for the username?

Other issues:

Your system may use a utmpx format rather than utmp.

Note the distinction between utmp and wtmp files.

Use the _PATH_UTMP and/or _PATH_WTMP macros that most sane systems give you,
in case the file isn't in /var/log...
