This CL refactors the bp2build code generator to pretty print lists with a single element on one line, instead of taking up three lines, which can make BUILD files unnecessarily long. A single line singleton list is also more commonly used in BUILD files. Test: TH Change-Id: Ic9e44741bbb070c8f45925466b9ccdd0608498b2
