Advice doom-profile-init-file to use our profile
`doom-start` locates the profile init file relative to
`doom-profile-dir` when running interactively, which we customize (either
directly or by setting `doom-profile-data-dir`). But when running
noninteractively, it uses `doom-profile-init-file`, which always loads
relative to `doom-data-dir`.

We cannot point `doom-data-dir` into the store, so this breaks us.

Work around it by advicing `doom-profile-data-dir` to locate the init
file relative to `doom-profile-dir` too. Try to make this more safe by
erroring out if called on a non-default profile.

All of this feels questionable, but I really want `doom doctor` to
work...
