fix(ftplugin/man.vim): hide signcolumn (auto)

Browse Source 
Problem:
It's a common practice to set 'signcolumn=yes' (always show) instead of default 'signcolumn=auto' in order to prevent annoying horizontal shifting in editable buffers when using some popular plugins that add/remove signs on the fly. This makes signcolumn always visible and breaks the text flow of pre-formatted man pages, even when no signs are actually defined. Some other options are already tweaked in man.vim to address the issue (e.g. 'nonumber'), but not signcolumn.

Solution:
set 'signcolumn=auto' in ftplugin/man.vim.
By default there is no |signs| in man pages anyway (and I am not aware of any plugins that could define them in man pages), so 'signcolumn=auto' should behave like 'signcolumn=no', i.e. hide the empty column in order to keep buffer width same as terminal width.
In a (rare?) case when user does define some signs in man pages, signcolumn will appear (breaking the text flow).
