Create Blivet standard partitioning with ext4 testcase.

This PR introduces a test case that uses the Blivet partitioning
tool to create a standard partitioning layout with / and /boot
(and specific partitions for UEFI and ARM64) using ext4 as
the selected filesystem.

It also adds a postinstallation test to check that the partitions
have been created correctly.
