s/send/sent for delsig in manpage

To reproduce run man gpg. This manpage is quite long but to press / to search the manpage for delsig read the line

  delsig Delete a signature. Note that it is not possible to retract a signature, once it has been send to the public (i.e. to a keyserver). In that case you better use revsig.
