overview-manual: Updates to "OpenEmbedded Build System Concepts"

Browse Source 
I removed the less than pretty build process figure and swapped
in the more aesthetically pleasing one.  Also, am refering to
the figure as the "general workflow figure".

(From yocto-docs rev: 093f1337131bc658d6afd1b56fb3661a76751aad)
