openjdk-17: omit DT_RUNPATH, move soft dependencies to suggests

Do not set DT_RUNPATH for OpenJDK binaries to prevent conflicts between
internal libs with present in $TERMUX_PREFIX/lib, specifically libnet.so

cups, x11 and others are not hard dependencies and shouldn't be necessary
in most cases. Move them to suggests .deb package metadata.
