mkosi: drop os-release symlink for minimal-base image

[  385s] ERROR: link target doesn't exist (neither in build root nor in installed system):
[  385s]   /usr/lib/systemd/tests/mkosi/mkosi.images/minimal-base/mkosi.extra/etc/os-release -> ../usr/lib/os-release

It shouldn't be even needed, everything should look in /usr/lib/os-release too
