fix(tvix/eval): src/compiler: ensure root_dir is absolute r/5120
Cppnix immediately absolutizes pathnames at parse time; if you write
`./foo`, it is immediately converted to `$(pwd)/foo` and manipulated
as an absolute path at all times.

To avoid having to introduce filesystem access operations in the
implementation of otherwise-pure builtins, let's guarantee that the
`root_dir` of the VM is always an absolute path.
