Travis: Use pip to install SCons on OSX

Not sure why we switched from homebrew to scons-local anymore, but pip should work just fine and is recommended by upstream. Downloads of scons-local from SourceForge were quite iffy, so this should help avoid CI errors due to not having downloaded SCons successfully. Setting Python's user binary PATH seems necessary on Travis/OSX as per travis-ci/travis-ci#5030 (confirmed that 'scons' is not in PATH without it).
