gpg-interface: do not use misdesigned strbuf_split*()

In get_ssh_finger_print(), the output of the `ssh-keygen` command is
put into `fingerprint_stdout` strbuf. The string in `fingerprint_stdout`
is then split into up to 3 strbufs using strbuf_split_max(). However they
are not modified after the split thereby not making use of the strbuf API
as the fingerprint token is merely returned as a char * and not a strbuf.
Hence they do not need to be strbufs.

Simplify the process of retrieving and returning the desired token by
using strchr() to isolate the token and xmemdupz() to return a copy of the
token. This removes the roundabout way of splitting the string into
strbufs just to return the token.
