refactor: Remove $build$src infix from munged paths

Browse Source 
Closure Compiler renames module globals so that they do not
clash when multiple modules are bundled together.  It does so
by adding a "$$module$build$src$path$to$module" suffix (with
the module object istelf being named simply
"$module$build$src$path$to$module").

By changing the gulp.src base option to be build/src/ instead
of ./ (referring to the repostiory root), Closure Compiler
obligingly shortens all of these munged named by removing the
"$build$src" infix, reducing the size of the compressed chunks
by about 10%; blockly_compressed.js goes from 900595 to 816667
bytes.
