package/clamav: add missing BR2_TOOLCHAIN_HAS_SYNC_4 dependency

In commit 203725a46bc6b61ed7e4fdb3d76f62327d3e47fa ("package/clamav:
bump version to 1.0.1"), select BR2_PACKAGE_JSON_C was added to
BR2_PACKAGE_CLAMAV without propagating the BR2_TOOLCHAIN_HAS_SYNC_4
dependency from BR2_PACKAGE_JSON_C.

Since at the same time a dependency on
BR2_PACKAGE_HOST_RUSTC_TARGET_ARCH_SUPPORTS was added to clamav and
Rust is not supported on the few architectures that don't have 4-byte
sync intrinsics, this has basically no effect, but ensure a correct
propagation of dependencies.
