Fix Tramp for Android 7

* tramp-adb.el (tramp-adb-ls-toolbox-regexp):
Username part of prompt is empty on Android 7.
(tramp-adb-ls-toolbox-regexp):
Ignore addition links column on Android 7.
(tramp-adb-get-ls-command):
Dont use --color=none when using toybox (Android 7).  It's not
possible to disable coloring explicitly for toybox ls.
