Reworded to: "because local directory override has too low priority".

Attached v2 patch that should solve all the above.

Added two 'guile' flavours:
    inplace/guile (to be used inplace)
    store/guile (to be installed to libexec)
While at it moved 'guix-daemon' to 'inplace/' as well to make it clear that
tests use inplace variant sometimes. Installation location did not change.

Also moved scripts/guix to inplace/guix as ./pre-inst-env relies on it to
be injected to PATH.

It's a bit hard to test right now as guix-master is slightly broken due to
missing installed files when installed as a primary package manager, but at
least fetch part works fine:

$ guix pull
