This commit removes the now outdated `HibernateEntityManagerCondition`
in favour of a simple check of `SessionImplementor`. As of
Hibernate 5.2, a single `hibernate-core` jar is required so a single
class check is enough.

Update CI scripts so that command failures do not cause an immediate
exit. Prior to this commit, some of our looping logic would never run
because the entire script would exit.

Update Gradle archive tasks to ensure that `META-INF/` and
`META-INF/MANIFEST.MF` remain as the first entries of the archive.

Prior to this commit, rewritten archives would violate the implicit
specification of `JarInputStream` that these entries should be first.

Update `NettyWebServerFactoryCustomizer` to deal with the fact that
Netty treats `0` and negative connection timeout values differently to
Tomcat, Undertow and Jetty.

See gh-16535

Update `PropertyMapper` to correctly combine predicates when repeated
calls are made to `when` and `whenNot`. Prior to this commit, subsequent
invocations would replace the previous predicate.
