pacman-key: add a default keyserver timeout value on --init

The default is supposidely 30 seconds from the gpg manpage, but that
sure wasn't what I was seeing- it was somewhere closer to two minutes of
silence. Add a more reasonable 10 second timeout value which should be
good enough for any keyserver that doesn't totally stink at it's job.
