    Cygwin: 3.4-only: uname: drop dot from external release info
    
    Right now, the dot between the version and the machine info in
    the release field is expected to come in from CYGPORT_RELEASE_INFO.
    But that's just confusing and doesn't match what we now do in 3.5
    since commit 97eb64b909bc ("Cygwin: uname: generate default release
    string from git as well")
    
    Add the dot when attaching the machine info.
