Remove rpm depency from packagesystem!

[krolmiki2011]

Thanks to these changes, it will be possible to eliminate the rpm dependency from bootupd and become more distribution-independent!

KEY CHANGES:
BIOS:
In the case of BIOS, ContentMetadata is created just as it is for UEFI; for BIOS, grub2-install --version and the mtime are used.
EFI (ostree-boot):
The situation is similar for ostree-boot in BIOS mode, except it iterates through files, and the version format is: legacy-ostree-boot-{mtime}

NOTE:
The old code, before the modification, is in the {bios, efi, packagesystem}_legacy.rs

Oh, and 'grub2-install --version' need package maintainers to patch grub2 upstream version to package version

This patch was inspired by issue: #468

Hi @krolmiki2011. Thanks for your PR.

I'm waiting for a coreos member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
