fmf: Use mkosi/mkosi.local.conf if the mkosi/ directory exists

https://github.com/systemd/systemd/pull/36954 will move all the mkosi
configuration in the systemd repository into a mkosi/ subdirectory. This
means we have to put mkosi.local.conf in that subdirectory as well, so check
if the mkosi/ directory exists and put mkosi.local.conf in there if it exists.

The mkosi/ directory will conflict with our checkout of mkosi so we move that
checkout one level up. Additionally, we can't use .. anymore as the package
directory as that only works when mkosi.local.conf is in the top level directory
of the repository so we use an absolute path instead.
