We currently use a mix of <option> and <computeroutput> tags for command
line options.  This commit changes them to all <option>.

Also make consistent how options with multiple names (eg. -h --help) are
shown.

Also, remove section describing --help and --version in Callgrind's chapter;
these aren't necessary and are presumably a hangover from when Callgrind was
a separate tool.
