[PATCH][meta-gplv2] gnutls: add older gnutls compatible with nettle

[Martin Jansa <martin.jansa@gmail.com>]

* gnutls depends on nettle-3.1* since 3.4.0:
  The requirement for nettle was bumped from 3.0 to 3.1 in gnutls_3_4_0
  https://gitlab.com/gnutls/gnutls/commit/c84129af91b21d33ffe086e507632771b0e76498
  and from 2.7 to 3.0 a bit earlier also in gnutls_3_4_0
  https://gitlab.com/gnutls/gnutls/commit/3fa80cf68919f07b3351b2722278ba463d6e731c
* add recipe for last release in 3.3 branch which is compatible
  with nettle 2.7.1 used in meta-gplv2
