[geary] Bump library dependency min versions to reflect reality.

commit d4aaa3c55197d772fa9135beca87cb3cc4b9638c

    Bump library dependency min versions to reflect reality.
    
    Commit 43341cd3 basically means we require vala 0.38, which excludes
    Debian 9 (stretch), Ubuntu 16.04 (artful) and Fedora 26. Hence bump
    minimum versions (and tidy up the list of deps) to reflect this.
