This is clone of RHEL-16881 for the leapp component covering additional cases when the upgrade could be blocked due to the fsize limit.

AC:

• increase fsize limit for the leapp process to prevent errors when trying to create files bigger than the original limit

A possible minimal reproducer:
1. Create file that is large enough that is included in the archive, eg 10MB large log file
dd if=/dev/urandom of=/var/log/leapp/leapp-preupgrade.log bs=1M count=10
2. set fsize limit: ulimit -Sf 10000
2. run leapp preupgrade
3. leapp fails with a traceback on attempt to create the tarball

Similar issues could be hit when the leapp.db file is bigger than the set fsize limit.
