package/tiff: fix host package

Disable webp and zstd on host package to avoid the following build
failure with host-gdk-pixbuf raised since bump to version 4.5.0 in
commit 5b62ea0136:

Run-time dependency libtiff-4 found: NO (tried cmake)

../output-1/build/host-gdk-pixbuf-2.42.10/meson.build:330:2: ERROR: Dependency lookup for libtiff-4 with method 'pkgconfig' failed: Could not generate cargs for libtiff-4:
Package libwebp was not found in the pkg-config search path.
Perhaps you should add the directory containing `libwebp.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libwebp', required by 'libtiff-4', not found

[...]

While at it, also disable libdeflate even if no build failures are
raised by autobuilders
