nixos stage-1: fix init existence test

The previous version contained a false positive case, where boot would
continue when the stage 2 init did not exist at all, and a false
negative case, where boot would stop if the stage 2 init was a symlink
which cannot be resolved in the initramfs root.

Fixes #49519.

Thanks @michas2 for finding and reporting the issue!
