utility-tasks.bbclass: add automatic version check for GIT/SVN proto

both git/svn supports remote information query: 'git ls-remote', and
'svn info'. With them, now upstream version will be automatically
checked for git/svn packages.

In the meantime, manual latest version tagged in distro tracking
fields are also compared as one alternative if upstream check fails.
Also such check is one indicator whether tracking field is missing.
