[fix] devel/jdk/{21,25}: Fix missing call to generate_atomic_entry_points on aarch64

I've been reviewing the jdk code base as part of the bsd-port
upstreaming efforts. I noticed we were missing a call to
StubGenerator::generate_atomic_entry_points() on aarch64. This
likely would have an impact on cpus that support HWCAP_ATOMICS
such as Apple's M2 processor. Although I don't have a test case
this fixes, this has been reviewed by my fellow bsd-port developers.

okay?
