gnutls.pc should not directly link to libz.so in Libs.private

[Matthieu Gautier]

# Description
In /usr/lib/x86_64-linux-gnu/pkgconfig/gnutls.pc installed by libgnutls-dev :

Libs.private is used by pkg-config to give link flags when using the "--static" option.

So Libs.private should contains internal libs used by gnutls to allow user to link statically with
gnutls.

If there is a direct link to a .so file, it's break static compilation.

The direct path to libz.so should be replace by "-lz"
