getuto: add manual timeout around GPG connection to keyserver.

Some kinds of ISP site blocks terminate connection after it is
established. This leaves GPG thinking it's connected successfully
and waiting for keys.
Add manual timeout invocations over keyserver calls. Set timeout
for them longer than GPG connection timeout.

Closes: #5
Closes: #6
