[Buildroot] [PATCH 4/5] package/gnutls: add optional dependency on brotli, zlib, zstd

[Arnout Vandecappelle (Essensium/Mind)]

Version 3.7.4 added compression options with brotli, zlib and zstd.
These are automatically discovered, which makes their inclusion depend
on the build order. Therefore, explicitly enable/disable them.

Note that the configure help text says "--without-brotli" and
"--without-zstd", but the options are actually --without-libbrotli and
--without-libzstd. --without-zlib is correct in the help text.

NOT for stable since 3.7.3 didn't have these yet.
