[Buildroot] [git commit] docs/manual: FOO_SITE must not have a trailing slash

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=c7ed1243a51352789b8130ebdd692b75b1e8cf07
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This has been the best practice since a long time, but it was not
clearly stated in the manual. Now it is mandatory, so mention it
explicitly.
