description:
bootstrap/bootstrap: allow the working directory to be a symlink

The working directory is only needed for bootstrapping pkgsrc, therefore
there aren't too many packages that can fail.

Loosening this check is needed for macOS, where /etc, /tmp and /var are
symlinks to /private, and using /tmp as the workdir for bootstrapping is
a sane choice.
