Stefan Fröberg eb1a657880 zlib: switch to a virtual package
The existing zlib package is renamed to libzlib, and zlib is turned
into a virtual package. This is done in preparation to the
introduction of zlib-ng as an alternative implementation.

[Thomas: define BR2_PACKAGE_PROVIDES_HOST_ZLIB as suggested by Yann
E. Morin.]
