package/libeXosip2: fix build for static linking

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

Add a new patch to use pkg-config to detect openssl.

Signed-off-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

To be noted: we're direly lagging behind on libeXosip2: we're at
version 3.6.0, which is at least two years old. There's now a 4.1.0
release. If time permits, I'll tackle this bump...

Would be very nice if you could!

I think the 'it' should be dropped here.
