    autogen: add shortcut for running scan-build
    
    scan-build is a static analyzer in llvm. As ususal static analyzers
    tend to mostly find theoretical bugs in software that has been in
    production for a while. For in-development code it can be useful to
    check if new issues is added as there is a chance to spot real problems
    before release. For systemd we are now down to 297 issues - the vast
    majority are false positives because the tool does not understand the
    cleanup attribute.
    
    Running clang's static analyzer scan-build is a bit messy. You have to
    run both configure and make "inside" the build-scan tool. To have an
    easy shortcut from autogen.sh I thus call both directly from it. This
    makes it different from the other options in autogen.sh. I chose 's'
    for static analysis.
    
    scan-build is in the package clang-analyzer on fedora.
