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.
