al2023: Remove duplicate logrotate entries

[cartermckinnon]

Description of changes:

AL2023 includes logrotate dropin config files for btmp and wtmp that conflict with our defaults. This removes the entries from our config in favor of the ones provided by the base OS.

> cat /etc/logrotate.d/btmp 

# no packages own btmp -- we'll rotate it here
/var/log/btmp {
    missingok
    monthly
    create 0660 root utmp
    rotate 1
}

> cat /etc/logrotate.d/wtmp 

# no packages own wtmp -- we'll rotate it here
/var/log/wtmp {
    missingok
    monthly
    create 0664 root utmp
    minsize 1M
    rotate 1
}
