java/bootstrap-openjdk17: Require compat14x

This port installs precompiled binaries which rely on libutil.so.9,
which is replaced by libutil.so.10 in FreeBSD 15 and up.

Note that this only helps platforms for which misc/compat14x is
available, i.e. i386, amd64, and aarch64. The port remains broken
on powerpc, powerpc64, and powerpc64le.
