[EFL] Add gnutls to jhbuild.module
https://bugs.webkit.org/show_bug.cgi?id=143777
Reviewed by Csaba Osztrogonác.
EFL port has required at least 3.0.0 version of gnutls since r176712.
However some old linux distributions don't support 3.0.0 version. Besides
other projects sometimes need to use lower version of gnutls.
This patch supports to download gnutls through jhbuild, and use it.
* efl/install-dependencies: Add nettle-dev dependency and remove libgnutls28-dev.
* efl/jhbuild.modules: Download 3.3 version because 3.3 version is stable version.
