Compile/Link with absolute paths for bundled/vendored deps. (#11129)

* Do not accept a path when using --with-bundled-lws.

The bundled library is always placed under externaldeps/libwebsockets,
when using the netdata-installer.sh script. When this option is missing,
we look for the system-wide installed version.

* Do not accept a path when using --with-bundled-libJudy.

The bundled library is always placed under externaldeps/libJudy. When
the option is not given, we look for the system-wide installed version.

* Use absolute header paths for repo-internal deps.

* Use absolute library paths for repo-internal deps.
