classes/base.bbclass: Locate the scm base path via BBPATH.
Currently, if the first item in BBFILES isn't in the main OE repository, the build fails entirely due to a ValueError. This isn't optimal. Rather than searching through BBFILES to find it, which could be slow when BBFILES contains thousands of files, let's just find base.bbclass and use that repository. Also, use better methods to find the git revision and branch, and identify the scm based on the existance of .svn/.git/_MTN to avoid calling out subprocesses unnecessarily.
