package/openjdk-bin: fix install

Create $(HOST_DIR)/bin and $(HOST_DIR)/lib otherwise build can fail on:

cp -dpfr /home/buildroot/autobuild/instance-2/output-1/build/host-openjdk-bin-13.0.2_8/bin/* /home/buildroot/autobuild/instance-2/output-1/per-package/host-openjdk-bin/host/bin/
cp: target '/home/buildroot/autobuild/instance-2/output-1/per-package/host-openjdk-bin/host/bin/' is not a directory
package/pkg-generic.mk:276: recipe for target '/home/buildroot/autobuild/instance-2/output-1/build/host-openjdk-bin-13.0.2_8/.stamp_host_installed' failed
make: *** [/home/buildroot/autobuild/instance-2/output-1/build/host-openjdk-bin-13.0.2_8/.stamp_host_installed] Error 1
