bug#23907: 24.5; tramp-use-ssh-controlmaster-options default value

[Thierry Volpiatto]

Hi, I see that `tramp-use-ssh-controlmaster-options` is still set to
non-nil by default in emacs-25, for some reasons, this hang emacs when
loading tramp with most recents versions of ubuntu and linuxmint and I
have several bug reports about this in helm.

What about disabling this by default ?

Thanks.
