Make getVersionInformation always return a VersionInfo

...even for JREs not listed in javavendors.xml, making it default to a
VersionInfo with sMinVersion = "1.8.0".

3d27b2fa9c5a03f78e5145377402f8a88e3da1be "tdf#124503: Support JRE installations
with unknown java.vendor property", which had changed getVersionInformation to
return an optional<VersionInfo>,  said in the commit message:  "For simplicity,
assume that any versions of such JREs are supported.  Our baseline is Java 6,
and there are unlikely any older versions of JREs from unknown vendors out
there."  Our baseline is Java 8 by now, and there are still unlikely any older
JREs out there, but for macOS ARM64 we may want to restrict to at least Java 17
implementing <http://openjdk.java.net/jeps/391> "JEP 391: macOS/AArch64 Port",
and this commit is a prerequisite for such a change (where we would then e.g.
change the hardcoded "1.8.0" to "17" for just that one platform).

(OtherInfo::compareVersions in jvmfwk/plugins/sunmajor/pluginlib/otherjre.cxx
unconditionally returns 0, meaning "versions compare equal", so introducing a
default version of "1.8.0" should have no negative effect on any JREs that use
OtherInfo.)
