Skip UEFI or BIOS on none hybrid partition layout

[HuijingHei]

• When booting with BIOS and no ESP device detected, skip UEFI checking
• When booting with UEFI and no bios_boot partition found, skip BIOS checking

Fixes #717

[HuijingHei]

The CI will not cover related testing, do some testing manually on none hybrid partition layout:

Additional info, need to run semanage permissive -a bootupd_t before testing:

on BIOS

root@fedora:/home/fedora# bootupctl status

This looks sane to me...I assume you tested it on the target env?

Yes, see #729 (comment), do some testings on silverblue using BIOS or using UEFI, both work. Will update this according to your suggestion and do testing again.

Will update this according to your suggestion

I think this can be a followup, no need to block on it.
