[v1] docs/manual/quickstart: Update output directory contents documentation.

The documentation for the output/host/ directory has been updated
to mention that it contains the sysroot for the target toolchain,
as well as the host tools required for running buildroot.

The staging/ documentation has been updated to reflect that it is
a link to the target toolchain sysroot in the host/ directory.

A commit log should not be written using present perfect, but at the
present. Simply: "This commit updates the documentation to reflect ..."
or something like that. I suppose you're a native English speaker, so
you'll be much better than I can be at finding the right formulation.

Here as well "has been updated" is confusing.

We still need your Signed-off-by here.

As of today, it is in fact not true that the sysroot contains all
userspace packages selected for the target. Only packages that have
_INSTALL_STAGING = YES are installed in staging. Perhaps we should
rephrase this last sentence to something like:

	It contains the headers and libraries of all user-space
	packages that provide and install libraries used by other
	packages.

Other than that, looks good to me. If your SoB line had been present, I
would have applied this version of patch and done the small tweaks
suggested here myself, but we really need your SoB.

Thanks!
