Revert "kernel-install: also try to find $BOOT by partition GUID"

This reverts commit 41f39e2144c935868059e894c1a1e13803e3568f.

From the post merge comment in #26648:

> Hmm, this is highly problematic, no? if I boot from my ssd and then
> plug in a fedora live usb stick, then there will be two ESPs around,
> the one from my ssd and the one from the live usb one, and this code
> might find the wrong one and bad things will happen
