Upgrade alpine and remove customisation for JNA in the fits image.

[nigelgbanks]

The following has been merged in aports:

https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/34087

Which should fix the issue where we had to have customisation to the jna packages for fits to support arm builds.

After upgrading to 3.15.5 when it releases we should be able to cleanup:

isle-buildkit/fits/Dockerfile

Lines 60 to 78 in c85af8b

	RUN --mount=type=bind,from=build,source=/packages,target=/packages \
	--mount=type=bind,from=build,source=/etc/apk/keys,target=/etc/apk/keys \
	apk add /packages/java-jna-*.apk && \
	cleanup.sh
	COPY --from=download --chown=tomcat:tomcat /opt/tomcat /opt/tomcat
	COPY --from=download --chown=tomcat:tomcat /opt/fits /opt/fits
	# Replace linux shared libraries with ones that target muslibc and are platform specific.
	# Also add perl for exiftool, and platform specific jna so native libs can be loaded.
	RUN --mount=type=cache,id=fits-apk,sharing=locked,from=cache,target=/var/cache/apk \
	apk add \
	file \
	libmediainfo \
	libzen \
	perl \
	&& \
	cp $(realpath /usr/share/java/jna.jar) /opt/fits/lib && \
	cleanup.sh

And remove the custom build: https://github.com/Islandora-Devops/isle-buildkit/tree/main/fits/build.

This will require testing on arm to validate that fits is working properly when calling out to native code.

Discussed briefly in the Tech call today; looks like you have a solid plan for this. let us know if you need more community input.

[nigelgbanks]

Even though they added jna back in for aarch64, we can't use it as it's compiled against a newer version of java, so we will have to continue using our own build package.

Upgraded to JDK 17 (The new LTS for JDK) to get around problems with Fcrepo deadlocking when receiving a SIGTERM. Might work now.

[nigelgbanks]

Yup that worked.
