docs/manual/quickstart: update output directory contents documentation

Browse Source 
Update the documentation for the output/host/ directory to mention
that it contains the sysroot for the target toolchain, as well as the
host tools required for running buildroot.

Update the staging/ documentation to reflect that it is a link to the
target toolchain sysroot in the host/ directory.
