[Buildroot] [git commit branch/2017.05.x] manual: patches are not applied for SITE_METHOD = local

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=acc0a4bb69ede02d0fe3a65561ad1b1daa2aa18d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2017.05.x

We had several remarks on the mailing list of users that were surprised
that patches were not applied for packages whose SITE_METHOD is local.
So document this.

Note that for OVERRIDE_SRCDIR itself it is already documented:

  When Buildroot finds that for a given package, an
  <pkg>_OVERRIDE_SRCDIR has been defined, it will no longer attempt to
  download, extract and patch the package. Instead, it will directly use
  the source code available in in the specified directory.
