8313707: GHA: Bootstrap sysroots with --variant=minbase

[shipilev]

We don't need the fully bootable Debian installation to build against. Therefore, we can bootstrap with --variant=minbase. The sysroots are about 5..10% smaller then.

This would also make our builds more immune to issues like JDK-8313701. Note how RISC-V GHAs are fixed with this PR by dodging the systemd dependency failure.

Additional testing:

• GHA cross-compilation builds
