list_gnupg_ciphers: Pipe everything into /dev/null

Browse Source 
Firstly the printed binary path is in the wrong place. Reading the text, one assumes Ciphers coming next.
Secondly it doesn't make sense to check there for a missing gnupg installation. Before calling list_gnupg_ciphers(), there is a direct call for gpg --version. If that fails the whole text is scrambled and no error reported

Dropping the output from which allows to remove the space from printing the ciphers. The text is correctly aligned now
