sequencer: assign only free()able strings to gpg_sign 

The gpg_sign member of the replay_opts structure is of type `char *`,
meaning that the sequencer deems the string to which gpg_sign points to
be under its custody, i.e. it needs to be free()d by the sequencer.

Therefore, let's only assign malloc()ed buffers to it.
