sauce-connect: listify phases and run in correct order

patchPhase was being run after installPhase, causing patchelf to be
run on the left-behind binary instead of the copy in $out. Fixes:

  ```
  $ .../bin/sc
  bash: .../bin/sc: No such file or directory
  $ patchelf --print-interpreter .../bin/sc
  /lib64/ld-linux-x86-64.so.2
  ```
