fetch: allow command line --tags to override config

Originally, if remote.<name>.tagopt was set, the --tags and option would
have no effect when given to git fetch. So if
tagopt="--no-tags"

	git fetch --tags

would not actually fetch tags.

This patch changes this behavior to only follow what is written in the
config if there is no option passed by the command line.
